Hi guys. MOT time again and I was just checking the car over when I noticed that I only have one rear fog light (drivers side) I assume I should have 2 as there is the same stop/tail light bulb in the passenger side light unit. I've swapped bulbs (what crap fittings!) and no change, just the one drivers side fog light. Running lights ok, head lights ok, front fogs ok, brake lights ok, wiring looks ok, no fuse's blown. Any help would be much appreciated as MOT is on the 17th!
