These 3000k headlights are superb in some of the miserable spring weather we've been having in the UK recently. 6500k blueish LED light seems to totally disappear on damp/wet road surfaces to the point where you aren't even sure they're working. But not so the 3000k. They light up potholes, kerbs, road signs reflect well, parked and on-coming vehicles' licence plates reflect brightly, they cause less fatigue on my eyes in prolonged night driving and, above all, I stand out. I've not seen proper yellow headlights on any car in the UK in, maybe, 25 years.
In a sea of white/blue-white Range Rover/Audi/BMW headlights my car is the one people stare at as nobody has them.
They were easy to install (5 mins) and because the chip location is the same as the halogens I didn't need to adjust the headlight aim.
Perfect!
