What year, make, model? On my '87 you pull out the light switch to turn on the front fogs, and pull it out a second time to turn on the rear (which were installed but not connected in '87). On the older E an orange indicator in the center of the switch would come on to show the rear fog was lit - they turn on seperately from the front. Is there an owners manual for yours car available? some of the MB controls are a little esoteric in operation, and a manual helps. Regards
