EVIL CONSERVATIVE
I made my replacement interior LED assemblies for my vehicles. Cheap I got the LED's 10/$1 I think and a $.05 resistor. The outside ones I just left incandescent.
they work great for maplights, etc but domelights are a bit different because an LED has less diffusion.
I used these.... but I'd love to see a pic of what you built. Heck, I might even like to buy a couple.
