i used to have them on my car, but i took it off as it was too BRIGHT and blinded all the oncoming traffics

I was using the 10,000K
6,000K should be fine for a car without projector headlights...

but then again i might be wrong....
from my point a view doesnt matter what brand it is at least its CHEAP

hehehe....
i'll let all the guys answer all your question.....(sorry but this is all i know)
10,000K XENON ON THE LEFT HEADLIGHT & 6,000K XENON ON THE RIGHT HEADLIGHT (Dont know why but if you see the 6,000K in REAL life its WHITE NOT GREEN)
