JPJ officer maybe, police won't know. My friend was stopped because he use white light Halogen, but police say is HID....but if the officer is experienced guy, well depends on his mood lo.... ive seen few cars with projector 4300k, the light beam is pointing down, they dun really care about it... i think what they care the most is whether the light temp and beam angle can blind ppl or not like those reflector housing HID, some more with 5000K color temp and above, that one confirm kena gao gao...
