I replaced my map lights, dome light, and reverse lights with Diode Dynamics LEDs.
For the map lights and dome lights, I got their stage 2 bulbs in white. Install was really easy; I did it in my apartment's parking lot. All you need is a flathead screwdriver. The bulbs are noticeably brighter than stock, and it's a very clean white. I'll try to take a picture at some point.
For the reverse lights, I got the stage 3 bulbs again in white. Install was easy; again you only need a flathead screwdriver. These bulbs are insanely bright. It looks like I have HIDs for reverse lights.
Price wise, the bulbs aren't cheap, but they seem to be fairly well made if initial feel is any indication.
