I want to learn how to wire them. Do anyone know good website on how to - like how to figure out what Ohm resister i need for given number of LED's, and how to wire them?
 
its not for the Mustang. its for my T/A
I have nasty red interior dash lights. I'm changing Radio. i hate non-matching light color, and choice of radio with red lighted button and display is limited. SO i'm going to change the light bulbs on everything(my winter project for it i guess), and i figure i'll use blue LED, and buy pioneer radio with blue button...
