It's easy to remove, slide the lamp toward the front or back of the car (I forget which). It should slide along the body in one of those directions. Once you figure out which direction it moves, slide it in that direction about 1/4 inch. It's on a plastic spring, so you should feel some springy resistance. Once it stops sliding, you should be able to lift the edge you were pressing off the body with you fingernails. After you lift one edge of the lamp, it should be easy to remove the entire lamp. No tools are needed.
