31mm festoon bulbs were a little too big for the trunk but i just bent the clip a little and madde it fit. I installed the map lights first, then the dome, and then the trunk. While doing the trunk light I somehow popped the dome light fuse(10w) which caused the keyless remote to not work. I replaced the fuse with the spare in the fuse box and noe everything works fine. I got the 6 led 31mm festoon for the dome and the trunk. After the install, i would go bigger. I will eventually upgrade the dome to a 12. The map lights are fine as well as the trunk.
