Tools/Supplies Needed:
-microfiber cloth
-window cleaner
-new headlight bulbs
-tape measure
-tape
-1/4" socket with ratchet
Procedure:
Starting out with the repairs that only take time and no money.
First is headlight cleaning and I do have an in-depth video for this. Removing the headlight only takes a matter of minutes.
Once out, the rear headlight cover is removed and you can disassemble the projector assembly. Dust can slowly make its way inside the assembly, eventually baking on the glass, plastic, and chrome reflector surfaces cutting back on light output. Window cleaner and a microfiber cloth can be used, but be extremely careful with the chrome reflector as it’s very delicate. While at the reflector, it’s a good idea to inspect the condition as they are also known to peel, leaving a raw plastic no reflective surface underneath. If that’s the case with yours, you may be able to use a high resistant chrome type tape, replace the projector assembly with either an OEM or aftermarket unit, or replace the whole headlight assembly.
Next is aiming your headlights. Maybe your car was in an accident or due to worn suspension components, either could leave the lights out of adjustment. Your fuel tank should be about half full as this too can move the beam’s position. Light adjustment is done using a 1/4” socket, there are two movements for each light. There will be an up and down movement and a right to left movement. Headlight adjustments can be done by yourself or you can pay a mechanic to set them up.
As a rough overview on how to adjust the headlight, first find a level surface to park the vehicle facing a wall or fence which is fairly plain where you’re able to see the hot spots in the beam. There are a couple ways to start this out, you can either park the vehicle a few feet from the wall, use tape to make the centerline of the beam and then move the vehicle back to 25ft from the wall. Or I started with 25ft from the wall and measured the center of the headlight on the car instead. This is just a generalized distance, this distance may vary specifically for Volvo.
You’ll also need to determine the centerline of the vehicle on the wall, I typically just eye this but you can run straights to help align everything. The lights should be pointing directly ahead of each other. The low beam will be about a couple inches lower than the centerline while the high beams should be on the centerline of the lights.
Another view once that light is out. The adjustment closest to the grill is the left to right movement, while the other adjustment by the headlight retaining clip is the up and down movement.
Another issue can also be hazy or foggy plastic lenses and this can be repaired by either polishing the lenses which I do have an old tutorial on or you can replace the lights.
Next for the third issue is bulbs. I have halogen bulbs and these do deteriorate over time, while they still work the light output is less as they get older. A simple fix for this is purchasing new bulbs. There is a variety of bulbs available, you can use the standard versions, upgrade to a higher performance bulb, or perhaps an led or hid retrofit. When using higher performance halogen bulbs, do not increase the wattage. There is a very good chance you’ll melt the lens or reflector, requiring new headlights in the end.

Absolute champion for making the c30 videos! Would rate them as the best on UA-cam!
Thank you so much!
The headlight removal on this platform is just 😚👌
and like, many of the other fixable things are just insanely accessible
I honestly feel like the P1 volvos are underrated in their DIY and tunability.
LOVE YOUR CONTENT!
Top Vid. Thanks - I Echo what people have said - how nice of manufacturers to think of making light cluster simple to remove, and even better the reflectors removable. In my case, (a 2004 car, so to be expected) the chrome had completely burnt off the reflector and this was the reason for poor lights. I put some aluminium foil tape over the burnt areas, and it's made a massive difference to the light output, much better! Not as good I'm sure as new fully chromed ones, but for anyone on a budget, a good cheap fix.
Thank you for the compliment and sharing your experience! Definitely beats having to buy new assemblies which would be much more pricey.
I had to tear down my headlights completely and rebuild the wiring harness. The insulator was beginning to crumble away, leaving bare copper exposed. One of my reflectors was delaminated as well. I installed LEDs and also threw halos around the projectors. It was a VAST IMPROVEMENT.
Wow, sad to hear even the simple stuff doesn't last anymore. Thankfully my wiring was still good, but you're not the first to experience failing insulation on the wiring. I heard Ford was using some type of soy base on the wiring insulation, makes me wonder if Volvo had the same thing.
The labels of the up/down and left/right are backwards. The easy one to see near the removable pin nearer to the back of the light is the horizontal L/R adjustment and the harder one to see and find down low in the front of the headlight is the vertical or up/down adjustment.
Thanks!
great video on dim headlights but i am having trouble getting low beam zenon to shine better they seem to be too low and do not want to come up when i adjust, these are the automatic type and i have also done computer adjust with no luck, when i turn lights on the zenon bulb does its complete self test but shines to low on low beam, any help would be nice
Helpful video, thanks. Although The label of the adjusting mechanisms for up/down and right/left should be the other way around. Besides they do jam with the time and because of poor design are easy to break! Spray them with silicon lubricants and be gentle turning them.
Yes he has them labeled backwards
Great video. The right light was as simple as you've shown however I can't access one of the screws on the left hand headlight. There's some mechanism in the way and not sure about removing / moving this mechanism.
I have the same issue with my model. Anybody who knows how do deal with it?
Can I use LEDs for for 05 s40 without upgrading any electrical? Halogen or LEDs?
Can you make a video of a 2008 Volvo S40 how to replace head lamp wiring harness for low beam
do you know the kind of bulbs that's needed for a C70 2012 model? my dipped beam bulb needs changing. All the websites said I need a H7 bulb, bought one but it was the wrong fit...
Do you have a video on replacement of license plate bulb housing on the Volvo c30???
The only video I have is for the bulb replacement which is located here ua-cam.com/video/mP27RyFuI4Q/v-deo.html
My headlights wiring are all cracking and losing its properties. They goes off every time i come across some bumps
My lights are all very lightly flickering in the car and outside (headlights and interior lights both dash and overhead) I have no idea what this could be. I have a 2011 S40R….would you possibly know? Thnx
Good morning I have a 2007 s40 and I would like to know if it has ballasts and where they are...?
Depends on what your vehicle was ordered with new. They would be on the rear of the headlight assembly as far as I know.
Showed the "before," but not the "after"... did all of this actually make a difference?
How to you remove the projector from the other headlight that has the electric motor in the way of the screw?
I have the same problem. Did you figure it out?
@@josip9848 nope, i think you have to remove the sealing and go in from the front. A job i'm not willing to do 😞
Give the projector a solid push to disconnect the assembly from the adjuster. Once disconnected, it will be easy to swivel slightly to allow the 3rd pesky screw to be removed
Adjust the beam position till it sticks out them you can get at it at an angle.
I just did this and gentle force is required but it worked on both headlights.
I tried removing mine but the angle motor is on the way. Help
I had the same issue. He obviously edited out that part. A tip would be great
I solved this problem by using a soldering iron to melt a semi-circular recess into the lip of plastic surrounding the motor housing (I think, mine has an empty housing). See if that might work for you.
I would have thought it was a bum alternator.
