Thank you guys that is some interesting reading, I was offered a pair of OEM Zenon headlights projector assemblies with their small ballast that came from a salvage 1999 SL 500 no other parts are included,hence the post, are there two different versions for this car? This ones do not look like they have any moving parts in them, and yes they make the car look kind of cross-eyed but I will like to have them nevertheless, AND they are not cheap. Anybody have an original retrofit set for sale?
