do they have some sort of special holder for them? if not i can do that myself...already done it 2 times. it may not look as pretty as starting out with four white leds on a plug... but it has the same effect if not better... i think it looks ghetto like (real life example) the person couldn't afford to put neons in the front or the back... on my supra and civic i had leds in the front in the back and it made it look better... but now i just have red ones going to the exhaust tips for a cool effect
