i have a question for all those LED wiring buffs. Due to LED's maxing voltage at 4.7 or 5 Volts we would need a resister to hook them up to our cars right? well i saw people without them and i was wondering why? can anyone give me some help and info on wiring these suckers on???

 

There's a nice tech article on how to do this right. https://www.thirdgen.org/tech/leddash.shtml
