Mercedes W107 Switch This listing is for a Mercedes W107/R107 Interior Overhead Light switch. Works on any W107/R107 chassis SL-class models that have this switch, this should be 74-76 cars, though i'm not positive, so check the picture to be sure. The Graphic, which is typical to become worn on these switches is in LIKE NEW condition, many years left on this switch. It's also in good working condition. Just plug it right into your wire harness. These are a pretty common thing to go bad on these years classic Mercedes, if your switch is starting to feel funny and hard to press, this is the first step in a path that leads to having non working switch... Like I also said, these are a great replacement if your graphic is all worn out too. Thanks for looking!
