Fog lights are not designed to see through fog. They are designed to better light up the ground directly in front of your car so you can see the lines in the road to use as a guide. That’s why the white line on the right side of the road is called the “fog line”.
They are also fitted down low on the vehicle to try to get as far away from the axis of the driver's eyes to prevent as much glare coming back off the fog, smoke, snow dust etc and are preferably selective yellow (ie light with all the blue indigo violet tones subtracted because they're the wavelengths which reflect glare the most. Warmer tones like Yellow aid the eye with depth perception too. Blue white lights annoy elderly and aging drivers because aging eyes have trouble refocusing after being blinded by oncoming LED headlights. )
You don't. You just need the fog lights angled properly at the ground and be brighter than the headlights. The glare from the headlight won't be fixed with fog lights. Amber or white is then a personal preference.
@hydroaegis6658 The hotter the lamp burns the whiter and brighter the light and closer to blue on the Kelvin scale. Our eyes naturally react quicker the other end of the scale, red or orange dash illumination is clearer and quicker to read than other colours a yellow fog light likewise gives greater clarity as it doesn't reflect as much, up until the mid 90s cars in France had yellow headlights as it gave greater clarity for the driver and less glare for oncoming traffic.
And in the US, manufacturers don't require a rear fog lights either which is a bummer because they are really helpful in seeing a car ahead of you in the fog. Helps in the heavy downpour I see in my area when it rains. Then again I constantly see idiots who don't turn their lights on at all until someone flashes their lights at them. This is probably due to the gauge clusters being constantly illuminated on the newer vehicles instead of them needing to physically be switched on.
This all wrong!!! Fogs are set below low beams, at a certain width, with amber color between 3-4k lumens and are angled to cover the road and meet in the middle with the low beams that are usually 4-6k white, soft white to provide the best visuals for the human eyes. It's been proven over and over and over and over again.

Fog lights from the manufacturers are usually only meant for other cars to see you better through the fog, by giving them more light to look at and to be able to see more points of your car, which will give the oncoming cars a much better indication of how big your car is without needing to directly see you first. It's akin to ships and the lights they use. Fog lights weren't really meant for you to see better in the fog or at night. That being said, there are still cars that come with fog lights that function as both a marker light for oncoming traffic, as well as extra light output to go with your headlights. I think Audi has some of the best ones when it comes to extra light output. I believe they call them their weather lights. But, those lights are located inside the headlight housing, so they do not provide extra points of light on the car for other cars to see. There are plenty of really great aftermarket options, though. Morimoto having the absolute best option with their 4 banger led fog lights. Those can directly replace your current fog lights, if your car is one of the models they can fit the lights in, and they act essentially as a second pair of headlights, but stretch out significantly wider than any headlights. Allowing you to see across any ditches or fields on either side of the road. They're also plenty bright to punch through some mild fog. But, just know that in dense fog, there's nothing that can just magically light the way through it. As fog is just water droplets, it will just reflect any light you shine on it, and if it's dense fog, it'll just make the light bounce around and all you'll see is just more fog and not much more of the road. And no, the color does not matter either. I think people say that just because the closer to infra-red the wavelength of light is, the further it can travel through dust and gas. But, as we can't see infra-red, it doesn't make a difference to our eyes.
(my) front fog lights help noticeably to see the road markings during heavy rain downpour. I drive at much lower speeds during those situations though. At higher speed those couple of meters of extra visibility are pointless.
@@Leo-pd8ww yea my car is the same, but i definitely think it's far past time for fog lights to become an actual extra source of light to aid your headlights even further. They can add a significantly wider beam to see far off the side of the road at the same distance as your headlights, so you can see any animals that are looking to cross the road, and the further out you can see, the more time you'll have to react and make a decision. They could also have a highbeam setting just like headlights, so it's just a massive wall of light. This would work perfectly in combination with matrix led systems that can precisely cut out every car within the light, and allow that wall of light to always remain on, even with oncoming traffic, and never blind anyone.
Oh, my God, what crap you say here and people seem to naively believe you!🤦♂️ The whole 1st paragraph of your ‘clever’ text is completely false. Fog lights from manufacturers are always-not even ‘usually’, but always-meant for illuminating the road to allow driver see the road in fog. And they are not meant to mark your car for other drivers (as their first role at least). You say that helping others to see you is done via giving them ‘more light’-that’s exactly what you should do in fog if you wanna kill other drivers and yourself (as well as your passengers). It is incredibly dangerous to emit even slightly bright light in fog. Cause fog is tiny droplets of water floating above ground (and you did write that)-any light gets both reflected and diffused. Essentially you get a wall of light. Fog lights have a narrow horizontal beam, it is flat, wide and low so that it gets underneath the fog where it is usually one foot separated from the ground floating above it. Also fog lights are intentionally made somewhat dimmed compared to main lights. Intentionally less bright. *In order to see road in fog it is obligatory to turn off headlights.* If headlights are on, you get that ‘wall of light’ in front of you and deliberately not bright fog lights’ light gets lost in that sea of light. Secondly. Cars that have fog lights functioning as marker lights (or even as day running lights) have two separate sections in those modules, with separate reflectors or/and emitters. One section works as a DRL, the other section works as the fog light. DRL’s beam has the same shape as the one of high beam-in hits everything, including the eyes of other drivers. But it’s five to ten times less bright than the high beams. The shape of the fog lights is tremendously different (low, flat, wide, wrote above). Those two cannot be made with one and the same device, there have to be different sections/different emitters in it. Thirdly. Yes, it does matter what color the light is. Prove for that is the dispersive prism. The one from school (or from the Pink Floyd’s “The Dark Side of the Moon” album cover). The shorter the wavelength, the wider reflection angle the light has, and vice versa. Precisely for that reason rear lights and halting light of the traffic light are red-the longest wavelength in visible specter. The next ‘non occupied’ wavelength and a visible light color is yellow. Hence yellow front marker lights, turn signals, head lights in the past and even backing lights in the past. However the shape of fog lights’ beams, the dim of those and the rule “fog lights only, head lights off” affect more on how good you’re able to see the road in fog. Yellow color is additional to those three factors. In some states fog lights can be used with main headlights only (which is dangerous and stupid). There’s one trick you can do: make your main headlights yellow and fog lights white-in that case you will be able to see the road in fog. Still not as good as when using fog lights only (even the crappy ones from the 1990s, lol), but still it is something. Maybe make your low beams with two colors: White when on their own and automatically switching to yellow when the fog lights turn on.
Clear lens, with a yellow or amber LED bulb in the fog light housing. That’s how I have seen it look aesthetically pleasing while doing the most in a foggy situation.
@AveGuy1 sorry bro but you are definitely saying something dumb, they are meant for others to see you easily with more light cutting through the fog, it can honestly work both ways but it's main objective is for others to see you easily. It's probably best you do your research before saying "dumb things on youtube"
@@AveGuy1 Turn on your fog lights in thick fog and tell me how the reflection of the dispersed light back at you helps you to see any better. Clearly you have either never driven through fog, or driven a car at all…
Fog lights do help, it’s obvious, there’s no need to test them. However there’s a huge mistake everybody seems to be doing in this vid: When it’s foggy *switch off* your main lights if you have the fog ones. Main lights (low beams and especially high beams) emit way too bright and too tall beam that reflexes from the water droplets of the fog and you get a wall of light before you. Fog lights have flat, wide and a-not-so-bright beam, they emit light _underneath_ the fog where it floats above the surface of the road. So during fog turn on your fog lights and turn off your low beams (and God forbid high beams).
NOOO! Fog lights *are* to help driver to see in fog conditions and are *not* for other drivers to see you. Fog lights help in fog tremendously! (If they are not used that stupidly as shown in this vid of course.)
@@aleksandrnestrato In heavy fog much of the white lights just reflects off of the fog immediately in front of your car/truck/atv/snowmobile and just puts a bright white curtain in your field of vision. Any light that does make its way through dense fog is going to have a tough time reflecting off of something at a practical distance back through the fog to your eyes. The wavelength of the amber light (However) travels much easier through and past the water droplets that make up the fog, rather then reflecting off the droplets. Enabling the light to make its way much farther down the road to alert other drivers of your presents. Of course it does reflect off of the road back to your eyes a little bit, but reflecting off a car down the road and back to your eyes through heavy fog, not so much. You'll see their fog lights before you see yours reflected back to you.
@@lastwordindicator Oh, my God… Please, excuse me my boldness, but that all is so amateur-ish.😔 You seem to have peeped debris of information here and there and now are trying pile ‘em up. First. Fog lights do not work as you’re picturing here-it is how you imagine, but not the reality. I’ll say more on that in the end. Second. Light doesn’t act as you describe. You’re close, but not there. Light doesn’t reflect off the water droplet altogether-some portion does reflect from the droplet’s surface facing the incoming light, some greater portion gets inside the droplet, some portion reflects from the inner side of the droplet on its way out (the latter can get reflected a zillion times from the droplet’s inner surface), some portion of light eventually gets out of the droplet). Though it’s important how much of light is being reflected, it is more important what happens to the portion of light that gets thru the droplet. And here occurs what you’re trying to ‘explain’. When light travels at an angle between two transparent ambiances with different densities, it deflects, more so-different wavelengths deflect at different rates. Here is what you don’t say: Is it not only the longer waves (red ones) deflect less and shorter ones deflect more (you kinda want to have red or yellow light instead of green or blue), there’s also a benefit from monochromatic light (one color), cuz it deflects at more or less one rate, whilst white light has all the wavelengths and its dispersion gives chromatic aberrations (the rainbow), which distract driver a lot. A fog water droplet acts as a dispersive prism. Hence the beginning of your comment is loose. Light doesn’t only reflect from the fog, it gets tremendously dispersed as well. So, correcting your words it would be _“The wavelength of the amber light (However) travels much easier through and past the water droplets that make up the fog, rather than __-reflecting off-__ dispersing on the way into and out of the droplets”._ Which is incorrect as well, cause it also does get dispersed and reflected, but to a lesser extent than green, blue or violet light. The other ‘off thing’ is that you compare amber and white, which is totally inaccurate, cause amber is a portion of white and white has amber in it. Kind of a ‘logical asymmetry here’, but I’ll leave that. Now let’s talk fog lights. Amber/yellow fog lights are like 30 years not a necessity, white ones work absolutely fine on millions of vehicles in multiple regions of the Globe. All you’re trying to say about wavelengths is applicable to low beams and high beams that, if stupidly turned on, do really have to fight way through the fog. Cause they’re placed too high. Fog lights are hung low for a reason: they shine *_under_* the fog. Fog rarely touches the ground, it floats a foot or two above the surface. Car manufacturer engineers did notice that. The other very important feature of the fog lights is the shape of their light beam. It is wide and flat, very low to the ground. In order not to hurtle the fog, cause all those dispersions+reflections start to occur. Third important feature of the fog lights is that they are usually not bright. They are quite dim, in case the fog is nevertheless being touched by the beams for a short time, there’s no blinding burst of ‘light curtain’, just a moderate one. And there is a fourth feature, that somewhat belongs not to the fog lights themselves: they are not meant for usage with main headlights in the fog. Headlights are much brighter (even the low beams) and they bash light into the fog-they outshine dim and delicate fog lights, making them useless. In all other conditions you’re free to add fog lights to your mains (they are quite handy for illuminating sides of the road closer to the vehicle), but in fog they *must* be turned on on their own, alone. The ‘reflecting off a car’ crap is a total misunderstanding of the fog lights-they are not meant to illuminate other cars and make them visible to you. They’re meant for illuminating the road surface a dozen feet before you, so that you could know what you’re stepping on with the wheels of your vehicle. Your speed must be at minimum in fog, fog driving is essentially driving in very low visibility. Cheers, mate!
Btw its not for visibility but for others can see your low height lights through fog and can judge a vehicle is coming from front. Fog lights can be white or yellow and should be placed at lower height where fog is less near ground
I was going to say the same thing. I'm always amazed by people who complain something doesn't work when they don't understand how it's supposed to work. Like people that put "fog lights" on their roof or hood. True fog lights have a broad pattern with a hard vertical cutoff. They should be very close to the ground to throw light under the fog.
Some people suggest an off color. Some people dont care. I like mine to match the color of low beam and high beam. It really lights the mediate front of the vehicle and in some cases the far side of each side of car. They go outward. I know my old car really worked. I could see things my headlights couldn’t emulate.
Fog lights work best when you turn off the main headlights, there goal is to dimly hit the ground rather than the fog but that won't work if you keep the main headlights on as they will still hit the fog.
Great question my guy! My fog lights are not yellow! They are bright LED's I bought off Amazon. Made miles of a difference (pun intended 😂) compared to the halogen's from the factory
@@rammiq sure! I’m trying to find for switched fog lights (white and yellow) in the same housing for my Acura RSX. I will post when I find and install them!
The more you light up the fog the less you see, the less light you use the less the on comming cars can see you...... the fog lights are low and light up a wide angle so on comming cars can see you without getting blinded
*It's been proven time and time again amber fog lights work the best. The yellow at 3-4k lumens meets the low beam which are usually between 4-6k white and provides the best lighting for human eyes*
Front fog lights are designed to see the close-in, side of road edges better, than using the low-beam headlights alone. Front fog lights OUTSIDE America and Canada, are wired to also operate on park, then low and high-beam. We teach here, that under *severe* visibility conditions, that you drive with just the cars park (sidelights) and front fog lights ON. This action reduces the glare caused even by low-beam headlights, AND additionally, allows the front indicators to stand out more clearly to lead traffic, as headlights can often mask those front indicators. Here, your SPEED *must* be reduced, that speed may be as slow as merely idling along, or less than 50kmh, use your speedometer to judge. Do NOT outdrive your forward vision. For the US, simply stick to their use in conjunction with low-beam headlights under poor visibility, as mentioned above, since that market doesn't operate the function - as does the rest of Earth. When visibility is so poor, your cars REAR FOG LIGHT should be ON, its better than being slammed from behind! This lamp function, offers up to twenty times the luminous intensity over your cars regular taillights. Therefore; You MUST switch OFF the rear fog lamp the moment you can see well enough ahead. Do not use a rear fog light simply because of a slight mist, but do use them in dust storms, in wildfire smoke conditions, in torrential daytime rain on freeways or highways, or on dusty gravel roads. The worse the visibility, the better the function serves you. The function is oddly optional in the US, but the US Recommended Practice is SAE J1319. The global design rule is UNECE 38. The use of hazard-warning lights, in effect as defacto rear fog lights, is contrary to international law, held in The UN Road Traffic Conventions & Amendments to date, where the function is reserved for use at vehicle breakdowns and crash scenes. Spectrum note; it is true that "yellow light" (selective yellow), may be perceived to be softer to the eye, but such lamp can have up to 15% less luminous intensity, compared to a white-optic version of the same lamp, hence the move to white-optic front fog lights. Not hard regardless, to utilise a selective yellow bulb, often marketed as "all weather" bulbs, if you personally prefer. The bulb you use, must bear conformity markings (for compliance), usually stamped on the steel body. Do not increase wattage, in heavy fog, you seek less glare, not more.
The important thing about fog lights is that they are mounted low so as to maximise the angle between your eyeline and the line of the beam. this minimises the amount of back-scattered light that you are looking through (both by reducing the length of the beam looked through and by avoiding the peak back-scatter direction which is straight back)
Fog lights aren't so much for personal use, but in super dense fog to alert others of your presence further away. Yellow light does help you see better in the fog
In my experience, fog lights are great for seeing on wet roads at night cause the lights sit so close to the ground and can properly illuminate the road in front of you unlike your normal headlights.
Fog lights help, especially if they are amber or yellow. Yellow and amber have a different wavelength that doesn't reflect as bad in fog. Sadly people confuse driving lights with fog lights. Fog lights are aimed very low and wide vs a higher narrow beam on the driving lights.
I know I’m a kid I don’t have a car But am I opinion I think it does not go through. It only shows the blurriness it only shows where things are around you.
Do the same test without headlight please. Fog lights are mounted lower for a reason. White or yellow, they work better when the heads are turned off. And yellow is easier on the eyes and you can see better. If you can’t see then slow down to a safe speed with hazards. Be safe y’all
Fog lamps with the proper color temperature that are aimed properly do help. However, fog lamps are down low in an attempt to illuminate the road. They are not supposed to aid the headlamps when it comes to long distance visibility.
Driving lights are white. Fog lights are yellow. And 90% of all drivers out there have no idea they are supposed to be pitched towards the pavement. Lights up the road better and doesn’t blind the living hell out of everyone in on coming traffic or the people they’re behind through the reflection of there mirrors.
They really seem to help some. Is it illegal to burn them on the highway, or just illegal if another vehicle is approaching your truck? I wouldn't appreciate someone blinding me with their fog lights. Sorry, one more question... have you ever installed these powerful fog lights on the front of your truck, and if so did they help at all? I've seen trucks with 2 KC lights on a roll-bar in the bed and 2 more up front on each side of a winch... crazy 🤔
Don't use White LED, use the regular Yellow instead. Also, fog light are use to see the lane right in the front of your car, you need to see the ground to keep your car in the right lane not something from far away, that is the jobs of headlight
It's probably not a widely known fact, but fog lights are ineffective against fog. Instead, they serve a great purpose in making you more visible in these conditions.
Honestly I honey find it helps for really low cars I switched to a Genesis coupe and when it’s foggy out I NEED them on, it’s always honestly been optional in every other vehicle I’ve driven
fog lights aren't for your visibility, Fog lights are for on coming traffics to see you coming. Fog lights are on the lower part of your bumper. Due to halogens bulbs back then that create to much reflection on your headlights creating a blinding reflection back to both drivers. older model vehicles you were able to turn off the headlight and turn on the fog lights when in a fog situation. now with LEDs or projector headlights fog lights are being phased out on newer modern vehicles. I highly suggest people with Halogen bulb headlights should still turn on the fog lights so on coming traffic can visibility see you.
Depends on what bulbs you have I have 40k lumen auxito leds in my fogs and hikari eye of Megatron in my headlights and love both. Very bright yellow works very well as well in the dark and fog. Red is apparently the best color for night vision, thinking about going bright red fogs and see how it works, probably illegal but Ill just hit a button an it'll disappear or go back clear
It's interesting that the front fog lights aren't mandatory in European cuntries while the real ones are, the front ones don't really improve the visibility while their rear fog light works perfectly - it tells the drivers behind you your exact location, it's still visible while the rest of your car might have already sunk into thick fog
They are pretty useless. Even with yellow light. NHTSA says they are supplemental, it's nice to see the fog lights on the opposite side of traffic, but they really only help in really low visibility situations. The fog you were driving through made it difficult to see but doesn't look like thick fog. So the fog lights essentially did nothing.
Have to be amber and a flat spread beam adjusted to throw the light lower than your headlights. Anything else is a driving light and will ruin visibility.
Fog lights are supposed to be aimed down and to the side a tad to help you see the guide lines on the road in thick fog. Not to help you see further! There isn't a single light available that will help you see further. It's impossible 😅 ... can your lights see through a wall?? No.... think fog = wall lol
White fog lights makes the visibility worse. You need yellow or amber lights.
Not necessarily depending if their angled right, mine are white. They help but its very minimal.

Precisely for that reason rear lights and halting light of the traffic light are red-the longest wavelength in visible specter.
The next ‘non occupied’ wavelength and a visible light color is yellow. Hence yellow front marker lights, turn signals, head lights in the past and even backing lights in the past.
However the shape of fog lights’ beams, the dim of those and the rule “fog lights only, head lights off” affect more on how good you’re able to see the road in fog. Yellow color is additional to those three factors.
In some states fog lights can be used with main headlights only (which is dangerous and stupid). There’s one trick you can do: make your main headlights yellow and fog lights white-in that case you will be able to see the road in fog. Still not as good as when using fog lights only (even the crappy ones from the 1990s, lol), but still it is something.
Maybe make your low beams with two colors: White when on their own and automatically switching to yellow when the fog lights turn on.
YOu turn your headlights off and run your fog lights so that you can see the ground and follow the white line on the shoulder.
I don't call them fog lights...
They're more pot hole lights.
I call em turning lights
"These fog lights are so good, even ghosts are jealous - they can't hide in the fog anymore! Casper, you've been served an eviction notice."😂
I just love how he’s trying to convince himself it absolutely works
Clear lens, with a yellow or amber LED bulb in the fog light housing. That’s how I have seen it look aesthetically pleasing while doing the most in a foggy situation.
They’re not to help you see, they’re to help others see you
Wrong, people say really dumb things on youtube
@@AveGuy1just like you?
@AveGuy1 sorry bro but you are definitely saying something dumb, they are meant for others to see you easily with more light cutting through the fog, it can honestly work both ways but it's main objective is for others to see you easily. It's probably best you do your research before saying "dumb things on youtube"
@@AveGuy1 Turn on your fog lights in thick fog and tell me how the reflection of the dispersed light back at you helps you to see any better. Clearly you have either never driven through fog, or driven a car at all…
Foglights are to see the FOG LINE, to keep you on the road, when visibility is low, that white line is the fog line
Yep i was going to say go amber if ur cheap use vinyl amber stick on cover
Fog lights do help, it’s obvious, there’s no need to test them.
However there’s a huge mistake everybody seems to be doing in this vid: When it’s foggy *switch off* your main lights if you have the fog ones. Main lights (low beams and especially high beams) emit way too bright and too tall beam that reflexes from the water droplets of the fog and you get a wall of light before you.
Fog lights have flat, wide and a-not-so-bright beam, they emit light _underneath_ the fog where it floats above the surface of the road.
So during fog turn on your fog lights and turn off your low beams (and God forbid high beams).
Amber ones are better than the clear ones ..
For the most part your fog lights aren't to help you see through the fog, they are so other driver's can see you.
It’s to see the lines on the road. I can already see your headlights
NOOO!
Fog lights *are* to help driver to see in fog conditions and are *not* for other drivers to see you.
Fog lights help in fog tremendously!
(If they are not used that stupidly as shown in this vid of course.)
@@aleksandrnestrato In heavy fog much of the white lights just reflects off of the fog immediately in front of your car/truck/atv/snowmobile and just puts a bright white curtain in your field of vision. Any light that does make its way through dense fog is going to have a tough time reflecting off of something at a practical distance back through the fog to your eyes. The wavelength of the amber light (However) travels much easier through and past the water droplets that make up the fog, rather then reflecting off the droplets. Enabling the light to make its way much farther down the road to alert other drivers of your presents. Of course it does reflect off of the road back to your eyes a little bit, but reflecting off a car down the road and back to your eyes through heavy fog, not so much. You'll see their fog lights before you see yours reflected back to you.
@@lastwordindicator
Oh, my God…
Please, excuse me my boldness, but that all is so amateur-ish.😔
You seem to have peeped debris of information here and there and now are trying pile ‘em up.
First. Fog lights do not work as you’re picturing here-it is how you imagine, but not the reality. I’ll say more on that in the end.
Second. Light doesn’t act as you describe. You’re close, but not there. Light doesn’t reflect off the water droplet altogether-some portion does reflect from the droplet’s surface facing the incoming light, some greater portion gets inside the droplet, some portion reflects from the inner side of the droplet on its way out (the latter can get reflected a zillion times from the droplet’s inner surface), some portion of light eventually gets out of the droplet).
Though it’s important how much of light is being reflected, it is more important what happens to the portion of light that gets thru the droplet. And here occurs what you’re trying to ‘explain’. When light travels at an angle between two transparent ambiances with different densities, it deflects, more so-different wavelengths deflect at different rates. Here is what you don’t say: Is it not only the longer waves (red ones) deflect less and shorter ones deflect more (you kinda want to have red or yellow light instead of green or blue), there’s also a benefit from monochromatic light (one color), cuz it deflects at more or less one rate, whilst white light has all the wavelengths and its dispersion gives chromatic aberrations (the rainbow), which distract driver a lot.
A fog water droplet acts as a dispersive prism.
Hence the beginning of your comment is loose. Light doesn’t only reflect from the fog, it gets tremendously dispersed as well. So, correcting your words it would be _“The wavelength of the amber light (However) travels much easier through and past the water droplets that make up the fog, rather than __-reflecting off-__ dispersing on the way into and out of the droplets”._ Which is incorrect as well, cause it also does get dispersed and reflected, but to a lesser extent than green, blue or violet light. The other ‘off thing’ is that you compare amber and white, which is totally inaccurate, cause amber is a portion of white and white has amber in it. Kind of a ‘logical asymmetry here’, but I’ll leave that.
Now let’s talk fog lights.
Amber/yellow fog lights are like 30 years not a necessity, white ones work absolutely fine on millions of vehicles in multiple regions of the Globe.
All you’re trying to say about wavelengths is applicable to low beams and high beams that, if stupidly turned on, do really have to fight way through the fog. Cause they’re placed too high.
Fog lights are hung low for a reason: they shine *_under_* the fog. Fog rarely touches the ground, it floats a foot or two above the surface. Car manufacturer engineers did notice that. The other very important feature of the fog lights is the shape of their light beam. It is wide and flat, very low to the ground. In order not to hurtle the fog, cause all those dispersions+reflections start to occur.
Third important feature of the fog lights is that they are usually not bright. They are quite dim, in case the fog is nevertheless being touched by the beams for a short time, there’s no blinding burst of ‘light curtain’, just a moderate one.
And there is a fourth feature, that somewhat belongs not to the fog lights themselves: they are not meant for usage with main headlights in the fog. Headlights are much brighter (even the low beams) and they bash light into the fog-they outshine dim and delicate fog lights, making them useless.
In all other conditions you’re free to add fog lights to your mains (they are quite handy for illuminating sides of the road closer to the vehicle), but in fog they *must* be turned on on their own, alone.
The ‘reflecting off a car’ crap is a total misunderstanding of the fog lights-they are not meant to illuminate other cars and make them visible to you. They’re meant for illuminating the road surface a dozen feet before you, so that you could know what you’re stepping on with the wheels of your vehicle. Your speed must be at minimum in fog, fog driving is essentially driving in very low visibility.
Cheers, mate!
People say such stupid things
_Whenever it's foggy it helps to know if my headlights are aimed properly or not._
After putting yellow fog LED’s it makes a world of a difference
Btw its not for visibility but for others can see your low height lights through fog and can judge a vehicle is coming from front. Fog lights can be white or yellow and should be placed at lower height where fog is less near ground
😂😂😂 Yeah white lights helps with “white fog”.
Actually, the white lights makes the visibility worse.
Maybe if you understood how fog lights work then you wouldn't have failed. Yellow/Amber LEDs are what you need.
I was going to say the same thing. I'm always amazed by people who complain something doesn't work when they don't understand how it's supposed to work. Like people that put "fog lights" on their roof or hood. True fog lights have a broad pattern with a hard vertical cutoff. They should be very close to the ground to throw light under the fog.
@@unclemeat7310chill probably just using the stock fog lights on the car
LED’s suck as fog lights because they are only yellow to the human eye.
@@NoName-tz5jithat's dumb. if the fog doesn't see the one color it's afraid of, it's not gonna move out of the way!
@@NoName-tz5ji what other animals are driving your car?
Bro, you need to turn off the head lamps .
Not with leds like that yellow or amber and make sure u have them aim correctly
Some people suggest an off color. Some people dont care. I like mine to match the color of low beam and high beam. It really lights the mediate front of the vehicle and in some cases the far side of each side of car. They go outward. I know my old car really worked. I could see things my headlights couldn’t emulate.
Fog lights work best when you turn off the main headlights, there goal is to dimly hit the ground rather than the fog but that won't work if you keep the main headlights on as they will still hit the fog.
Help? Yes.
Help a lot? Help significantly?
Majorly?
That's another question for an expert to answer
Fog lights don't cut through fog to help you see ahead ... Their function is to make the car visible through fog for other cars and pedestrians
EXACTLY
Wrong
Yes and to add to that, they add visibility for you to see the road lines.
Kinda. I wonder if they were yellow 🤔
Great question my guy! My fog lights are not yellow! They are bright LED's I bought off Amazon. Made miles of a difference (pun intended 😂) compared to the halogen's from the factory
@@rammiq sure! I’m trying to find for switched fog lights (white and yellow) in the same housing for my Acura RSX. I will post when I find and install them!
My man! Looking forward to seeing your final product!
The more you light up the fog the less you see, the less light you use the less the on comming cars can see you...... the fog lights are low and light up a wide angle so on comming cars can see you without getting blinded
*It's been proven time and time again amber fog lights work the best. The yellow at 3-4k lumens meets the low beam which are usually between 4-6k white and provides the best lighting for human eyes*
Kelvins, not lumens ;)
Front fog lights are designed to see the close-in, side of road edges better, than using the low-beam headlights alone.
Front fog lights OUTSIDE America and Canada, are wired to also operate on park, then low and high-beam.
We teach here, that under *severe* visibility conditions, that you drive with just the cars park (sidelights) and front fog lights ON. This action reduces the glare caused even by low-beam headlights, AND additionally, allows the front indicators to stand out more clearly to lead traffic, as headlights can often mask those front indicators.
Here, your SPEED *must* be reduced, that speed may be as slow as merely idling along, or less than 50kmh, use your speedometer to judge. Do NOT outdrive your forward vision.
For the US, simply stick to their use in conjunction with low-beam headlights under poor visibility, as mentioned above, since that market doesn't operate the function - as does the rest of Earth.
When visibility is so poor, your cars REAR FOG LIGHT should be ON, its better than being slammed from behind! This lamp function, offers up to twenty times the luminous intensity over your cars regular taillights. Therefore; You MUST switch OFF the rear fog lamp the moment you can see well enough ahead.
Do not use a rear fog light simply because of a slight mist, but do use them in dust storms, in wildfire smoke conditions, in torrential daytime rain on freeways or highways, or on dusty gravel roads. The worse the visibility, the better the function serves you.
The function is oddly optional in the US, but the US Recommended Practice is SAE J1319. The global design rule is UNECE 38.
The use of hazard-warning lights, in effect as defacto rear fog lights, is contrary to international law, held in The UN Road Traffic Conventions & Amendments to date, where the function is reserved for use at vehicle breakdowns and crash scenes.
Spectrum note; it is true that "yellow light" (selective yellow), may be perceived to be softer to the eye, but such lamp can have up to 15% less luminous intensity, compared to a white-optic version of the same lamp, hence the move to white-optic front fog lights. Not hard regardless, to utilise a selective yellow bulb, often marketed as "all weather" bulbs, if you personally prefer. The bulb you use, must bear conformity markings (for compliance), usually stamped on the steel body. Do not increase wattage, in heavy fog, you seek less glare, not more.
Aren't you supposed to turn of the main beams when driving on heavy fog? They're low to reflect back the least amount of light possible.
You'd have to install a switch for that in a lot of vehicles. Stock the fogs won't come on if the lows aren't on.
Yellow polarized glasses is a must in these situation.
Depends on where you position them. My stock lights don't doo much . My pod lights however allow me to see 3 lanes wide on the road.
You're supposed to turn the headlights off and just use the fogs.
Yellow makes a big difference
Helps slightly..... Better than nothing man.
Of course they do, thats why they are called fog lights, but if you converted to yellow, it would make a huge difference
The important thing about fog lights is that they are mounted low so as to maximise the angle between your eyeline and the line of the beam. this minimises the amount of back-scattered light that you are looking through (both by reducing the length of the beam looked through and by avoiding the peak back-scatter direction which is straight back)
Not only do you need yellow/amber, but you also need to kill the white lights, as well
Good job telling someone to drive at night with their headlights off.
I put in the led switch backs yellow/white from lasfit and love them way better than stock. You should give them a try
Fog lights aren't so much for personal use, but in super dense fog to alert others of your presence further away. Yellow light does help you see better in the fog
In my experience, fog lights are great for seeing on wet roads at night cause the lights sit so close to the ground and can properly illuminate the road in front of you unlike your normal headlights.
Fog lights help, especially if they are amber or yellow. Yellow and amber have a different wavelength that doesn't reflect as bad in fog. Sadly people confuse driving lights with fog lights. Fog lights are aimed very low and wide vs a higher narrow beam on the driving lights.
White Fog lights should be angled towards the ground to be effective otherwise if the lights spread everything, it will be harder to see through.
Fog lights are just normal lights that are point out at the ground for better road visibility.
I know I’m a kid I don’t have a car
But am I opinion I think it does not go through. It only shows the blurriness it only shows where things are around you.
Fog lights do work...those not so much
To practically use fog light , turm off the main head lamps and keep just fog lights on
Amber or golden yellow fog lights will help
wherr is the location of your fog lamps?
Mostly mounted in the bumper. There are few models with fog lights mounted in the headlight (e.x VW Golf Mk4 and Audi A4 B5 Pre-facelift).
I would not be driving that fast in the fog.
Do the same test without headlight please. Fog lights are mounted lower for a reason. White or yellow, they work better when the heads are turned off. And yellow is easier on the eyes and you can see better. If you can’t see then slow down to a safe speed with hazards. Be safe y’all
Mounting location is everything.
Best way to see when it's foggy is to turn on the interior dome light. Visibility doubles. My Dad taught me this when I was younger.
Helps with spotting lines.
Fog lamps with the proper color temperature that are aimed properly do help. However, fog lamps are down low in an attempt to illuminate the road. They are not supposed to aid the headlamps when it comes to long distance visibility.
Driving lights are white. Fog lights are yellow. And 90% of all drivers out there have no idea they are supposed to be pitched towards the pavement. Lights up the road better and doesn’t blind the living hell out of everyone in on coming traffic or the people they’re behind through the reflection of there mirrors.
They really seem to help some.
Is it illegal to burn them on the highway, or just illegal if another vehicle is approaching your truck? I wouldn't appreciate someone blinding me with their fog lights.
Sorry, one more question... have you ever installed these powerful fog lights on the front of your truck, and if so did they help at all?
I've seen trucks with 2 KC lights on a roll-bar in the bed and 2 more up front on each side of a winch... crazy 🤔
These fog lights are just LEDs from amazon! They work really well in my opinion! I haven't tried others yet but hopefully will in the future!
They won't blind anyone. They're way too low
@@Undisputed_Kingdoesn't mean it can't be missaimed to be higher than the centre line visibility of where it's supposed to be
I just call them deer lights because they illuminate out to the side a bit and make it easier to see deer getting ready to run across the road
Don't use White LED, use the regular Yellow instead. Also, fog light are use to see the lane right in the front of your car, you need to see the ground to keep your car in the right lane not something from far away, that is the jobs of headlight
“Let’s try that again”
“What do you guys think”
Yeah bro if you can’t tell I’m gonna say no 😂
Yellow spectrum lights has been created for foggy and other public safety measures for safety first...
It's probably not a widely known fact, but fog lights are ineffective against fog. Instead, they serve a great purpose in making you more visible in these conditions.
I can see when I turn on night vision😊
Fog lights are only helpful if they yellow/orange colored. White or LED fog lights makes things worse visibility wise.
Projector fog lights especially the yellow ones work best in this situation, even white ones will work better than flood lights
Honestly I honey find it helps for really low cars I switched to a Genesis coupe and when it’s foggy out I NEED them on, it’s always honestly been optional in every other vehicle I’ve driven
The glare got worse
helps a LOT when they're amber
All the people complaining don't know that fog lights help you see line markers more clearly. They don't magically help you see through the fog.
I just drive towards the light when going through fog
Depending on the spot you install the fig lights
Fog lights are supposed to be yellow bc yellow light cuts thru fog much easier than white lights
fog lights aren't for your visibility, Fog lights are for on coming traffics to see you coming. Fog lights are on the lower part of your bumper. Due to halogens bulbs back then that create to much reflection on your headlights creating a blinding reflection back to both drivers. older model vehicles you were able to turn off the headlight and turn on the fog lights when in a fog situation. now with LEDs or projector headlights fog lights are being phased out on newer modern vehicles. I highly suggest people with Halogen bulb headlights should still turn on the fog lights so on coming traffic can visibility see you.
I think the better fog light I will use it is the light bar
Fog lights are not for driver, visibility but instead for other cars to see u 😂
Depends on what bulbs you have I have 40k lumen auxito leds in my fogs and hikari eye of Megatron in my headlights and love both. Very bright yellow works very well as well in the dark and fog. Red is apparently the best color for night vision, thinking about going bright red fogs and see how it works, probably illegal but Ill just hit a button an it'll disappear or go back clear
My fog lights help me a lot
I don't know what kind of fog lights you're running brother but they suck.
Hard to tell from the video, maybe the difference is more visible from the actual eye perspective 🤷🏽♂️
Yellow fog light help better visible.
It's interesting that the front fog lights aren't mandatory in European cuntries while the real ones are, the front ones don't really improve the visibility while their rear fog light works perfectly - it tells the drivers behind you your exact location, it's still visible while the rest of your car might have already sunk into thick fog
😂
Now change your fog lights to yellow or amber and test again… you will be shocked to see the difference..
I have amber Baja Design 45w “combo” beam fogs & they work very well.
They are pretty useless. Even with yellow light. NHTSA says they are supplemental, it's nice to see the fog lights on the opposite side of traffic, but they really only help in really low visibility situations. The fog you were driving through made it difficult to see but doesn't look like thick fog. So the fog lights essentially did nothing.
Have to be amber and a flat spread beam adjusted to throw the light lower than your headlights. Anything else is a driving light and will ruin visibility.
There's a reason why most offroaders use amber or yellow.. white foglamps are just the worst
Fog lights are for other cars to see you better
Do the turning signal have sequence, if yes how can I turn the function on
Technically those are Driving Lights. Not FogLights Fogs are Yellow to cut thru the thick fog
Always hard to judge lighting with cameras. The ultimate opinion and deciding factor is… If you think it helps then boom!
Id say they do, especially apparent on the reflective street lines
They look poorly aimed and color seems off.
I like turning on the fog lights regardless of if there is fog or not
You’re the worst kind of driver after drunks.
@@chrism9493
Turn your dipped beams off then see what happens
Aren’t fog lights so others can see you better?
Fog lights are supposed to be aimed down and to the side a tad to help you see the guide lines on the road in thick fog. Not to help you see further! There isn't a single light available that will help you see further. It's impossible 😅 ... can your lights see through a wall?? No.... think fog = wall lol
White lights are not fog lights there auxiliary lights , fogs are amber
Some idiots switch their halogen yellow fog lights that actuall works with white led lights….thats why they don’t see the difference
