In this video, I'm testing the Philips Ultinon Pro6000 Boost H4-LED bulbs in my 2015 Smart 453 (90hp). These LED bulbs are designed to be a road-legal upgrade for cars like mine, and you can check their compatibility with your own vehicle on the Philips website-just a quick Google search will help you find it.
While the light output is much brighter than my old halogen H4s and offers a wider low beam, the area just 1-2 meters in front of the car is a bit weak. This issue stems from my car's headlights, which weren't originally designed for LED bulbs. Additionally, I had to use larger dust caps that I printed myself, since the Philips bulbs have a big cooler that doesn't fit with the default dust caps unless you really know what you're doing. It's important not to use these bulbs without proper dust caps, unless you want wet and dirty headlights, which are difficult to clean.
Although these Philips LEDs can't be compared to full LED systems (which cost around $1,500 compared to the $100 price of these bulbs), they are still a worthwhile upgrade. Sometimes, you can even grab them on sale for as low as $70. The overall light output might not look perfect, but compared to what I previously had, this is definitely an upgrade. These lights take some getting used to, as my situation is a bit unusual. Instead of a typical cone of light, I get more of a rectangle of illumination directly in front of my car. If you have a different car, your light pattern might be much better. These bulbs also use much less energy than the halogens. The video, recorded in HDR to accurately depict the light output, shows that the reflections on traffic signs are overly exposed-something that's more noticeable on camera than in real life. While the high beams are very bright, they appear somewhat dirty with light spots in the video, though this effect is less noticeable to the naked eye.
