Hello, need some help here. I plan on retrofitting about 9 LED's per sidemarker. White high-intensity LED's. The car of course has anywhere from 12-14.5 volts so would wireing them in parallel make more sense? Since they will all get the same voltage and just draw the necessary current to light them up? Part #'s from digi-key or some source would be appreciated as well on what i'll need (incl' the LED's), thanks...
