Beginning today, everytime I place the car in-reverse the Lamp Out indicator light comes on. I had a friend check the rear and both lamps are working. I checked both bulbs and they are good, working german made bulbs (from the MB dealer). I switched lamps from side to side, still did not fix the problem.
Any ideas? PS. I hate to drive around with a light on the dash indicating something amiss, drives me crazy, so must fix.
