All of the bulbs that are controlled by the light switch go through the bulb failure monitoring unit. If one of the circuits fails, that bulb will not light and the light on the dash will illuminate. Also, if you have ANY ONE bulb that is out or of the wrong wattage, it will come on. Be sure to chech the tag illumination bulbs, they have gotten many techs. The control unit is inside of the fuse box at the rear and is about 3-4 inches long and about 1in wide. good luck
