Make sure you order the right ones... I ordered 2 sets that claimed they fit the E53. They did not. After modification I was able to get one installed but tested them by closing the door a bunch of times. The BMW roundel would rotate with each closing of the door. The little lens in there with the BMW roundel was not fixed... would have taken more modification. At this point I was done with them... Still have them in my garage.
