I just changed my dome light, map lights, and my step/courtesy lights. I had to look up how to remove the dome light cover...idk if most people know how to do this but I just didn't know how to do it. If you look closely at the edge of the clear plastic there is a tab on one side and two on the other. Just take a flat headed screwdriver (or knife) and push the tab back to pull out the clear part.
Removing the map lights were the hardest part. I couldn't get a good grip on the bulb to pull it out. What I did was I took a piece of string (smaller than a shoe lace) and tied it into a circle that would tighten around the bulb when I pulled on it. I used a knife (probably not the best tool to use but it was in my pocket) to push the circle to the base of the bulb then I pulled it tight. When I pulled on it hard, the bulb came out. Knowing this would have probably saved me a good ten minutes of struggling. I have also heard that the glove box light if difficult. I don't know if this is for the same reason or if this technique will work. If someone knows please post incase someone is needing help with that light. Oh, I highly suggest putting LED's in the interior...it looks so clean.
