I made a set of angel eyes with LEDS and love it. Check out the car at cardomain.com/id/willisbr
Anyways...12 volts is fine to use but you must use resistors orr you'll burn em up quick. White leds are the best and brightest...but if you dont use enough resistance and get to much power, the wwhite LEDS will have a blue tint. no good./ You probably want to go with white LED with a colored plastic lense to go through. research online to get the best resistance quotes...because 1 resistor off can burn a whole set of lights if your running a series circuit. Good luck and keep us posted!!
Yeah, definitely keep us posted. The G35's taillights are downright SEXY with all their LED-ness, and if you can get this to come out well, I'd definitely be interested in getting a set on my car..
