Mercedes Door Reflector This listing is for a Mercedes Door Reflector. This is from a w126 chassis car, it snaps into the edge of the door so your open door can be seen by other cars at night when it is opened, a important safety feature! These commonly fall out or break, causing you to have an unsightly HOLE in your inner door so check to make sure you have all of yours! Part number is 126 820 00 74 / 1268200074 The reflector is in great shape, with all the mounting tabs intact, the rubber surround is also in good shape. Thanks for looking!
