when we go up the ladder of temperature of HIDs and say that you are losing light "OUTPUT" we are not meaning how bright they LOOK.... YES the 12000K are real bright and you can tell even in Africa.........But when we say "OUTPUT" we mean the light beam from looking INSIDE the car.... any temperature above 4300K you are LOSING light output. I wouldnt be surpirsed the OEM lightbulb will give you better vision than the 12000K HIDs. <--- abit exagerated but you get my pointspeedmo21 said:no i have the purple bulbs now,there nice but not HID...my buddy just put the 12k in his RSX and it looks increidble..i could tell it was him in ****** africa...these lights are unmistakeable
