I think I bought some german 6000 kelvin hid upgrade bulbs for my car on ebay. Well, I think it was ebay, I was looking there a lot. I had one of those gators flip up and hit my headlight going down the highway b/c some mom was driving her minivan on the road while on the phone and ran straight over that thing and it flipped it up right into my light and it smacked it with a ton of force, then scratched my hood and down the side of the car with the little metal stuff inside the tire tread.
Anyhow, my new bulbs are amazingly awesome. They are the right rated bulb for the hid's I was replacing, the only difference was stock was 4200 k and those were 6k k.
