I just replaced my map and rear inside dome lights with LED's from superbrightleds.com. What a difference they make! The lights are so much brighter and really make it look clean. It took me maybe 5 minutes to complete.
I followed the thread (linked below) to show me a quick run through on how to remove all the peices to access the bulbs. The write up was great and I highly recommend anyone else thinking of doing this to follow this write up.
