pop your trunk and there should be plastic type screws on the trunk liner on the sides, not on the floor but on the sides. There a wing nut type screw so you can do it by hand, once those are out you can peal back the trunk liner and there are several screws w/ bolts on them that hold the lights onto the body. Unscrew the bolts and just pull, they will come right out. They should pull right off pretty easy, if not dont yank on them b/c you prob missed a screw just look for it, make sure you have a flashlight if your not in a well lit area so you can see better.
I sprayed painted my lights this past Nov b/c I had one new one and one used one and one was fadded more then the ohter so I painted them both. I did the same thing that 1105 did. I took them off, taped them up and painted them glossy black. I did sand them down some just to get a better surface for the paint to stick to. I used Krylon interior exterior paint. I also used a few coats of clear coat for the hell of it. They look really good, alot cheaper then taking them to a shop. Just take your time and dont rush it and they will look fine.
