Rear Fog Light Question - I have a dash light showing burned out light when i switch on the reag fogs. I went to replace the bulb and there is a factory pastic "bar" preventing a bulb from entering the housing, on rear driver side (left side). I rememebr from my time in Europe that "fog light" sometime meant a single left or right "brighter" bulb. Is this why the factory blocked the rear driver fog light?
