Hello everybody. I installed my D4S bulbs for my GS 350 low beam this morning, and i turned it on earlyer while i driving, the low beam light turn out purple instead of white blue. Is that normal or happen to anyone with 8000k on the projector.
Color can vary between one brand of bulb to another, generally if you want white with a little blue I wouldn't go higher than 6000k. A lower color temp will have more output as well.
