I will soon be changing all of the interior bulbs in my truck to red LEDs. I'm working on getting a new cluster face to do some testing on before I change all of the lighting out on that.
I just ordered new LED bulbs for the ashtray, cup holders, ignition switch, dome light, map lights, glove compartment, radio, and the AC/Heater knobs. The total came to almost 60 dollars, but that is with shipping. I did also order a few extra bulbs just in case.
I'm planning on doing DIY for each area when I do the install as well. It's not going to be anything major or amazing, but I hope it will inspire others to add their own personal touch to their vehicles as well.
Also I will install a CD player with red LED faceplate as well to help finish off the look. I can not forget about the door switches as well.
Before I leave this thread, I know what everyone will say until I get my pictures of the modifications being done:
