Review on 💡 H4 LED Headlight Bulb: High/Low Beam Conversion Kit, 60W, 10000LM - Cool White-6000K by Derek Dolla

Installation is extremely easy but properly installing it on your vehicle while retaining the factory quality assurance elements such as the rubber dust cover I think will be of the utmost importance Depend on you specific car. I have a 2006 Pontiac Vibe. It took me about 15 seconds to install, but then I found that the rubber boot that protects the flashlight body from water and dust just didn't fit. Even if you pull it on very firmly and forcefully, the boot sits on the cooler fins running on the outside. I could feel how hot these things get after ten minutes of driving and I just can't believe they aren't going to melt and cause problems. I rode them in the rain. These lights rotate 360 degrees inside the case once installed, which is good and bad. If they only fit one way I would know if they are positioned correctly. I rotated them a few times, first adjusting the reflector's beam shape to the standard halogen and then to a few other positions. They look amazing with really clean white light and they look bright when you're in front of the car, but in the rain they gave off so little light that I didn't feel safe driving them. I really wanted them to work because honestly they cost the same as regular halogen bulbs and look way cooler. I ended up returning them because there were too many potential problems and I couldn't set them up as good headlights.
