i just put in over 70 leds this weekend! all 5mm blue. foot well, ac control, all window switches, 4x4 selector, rear wiper, headlight switch, side mirror bottom lights, dome curtosy(spelling fail) front and back, bottom door markers. like i said all 5mm that cost about .06 a pc and resistors .04 a pc and shrink tube .50 a ft. save money and solder your own bulbs. i made my own 194 bases with common terminal connectors, hot glue and shrink tube.
i will post some pics from my phone soon
