Just installed on w126 Depo headlights, but bought from some website. Well driver side fit perfect, but passenger side barely can fit since my car has a bracket for the air filter. So I will need to cut one of the bracket post, if I wanted in the future to replace bulb without removing whole headlight. Another problem is headlight wipers, it's useless thing, but it's part of the car, so driver side I have less problem just drill another whole in the wiper motor bracket to secure on two bolts. Passenger side is not even close to mount wiper motor, so I secured it by one bolt that goes into body and make an adopter plate between wiper bracket and headlight mounting place. So it will be secure by just two bolt. I don't care it's enough to keep it in place. I don't think my wiper even working.
