Hey guys, I have some 3v, 20mA LEDs that I want to install in my car and i was wondering what stuff i would need to do from start to finish. If any of you would mind spending the time explaining it to me please? Installing LEDs? -- posted image. I'm mainly confused in where i tap to get the power, and fusing.

thanks in advance

oops, my bad, i forgot: volts/current= resistance

and in my case 12v/80mA=150 ohms

ok so i've got that covered now where do i get the 12 volt source? what wire(s) should i tap into?
