For the rear fog I use a round LED one I got off e-bay for around £10. Its about 3" dia and being LED its flat so you don't need to make a big hole in the body work. Lasted well so far. I also used LED fogs off e-bay. I use them as day running lights so I wanted LEDs to cut the current draw. I recently fitted an LED high level brake light strip across the top of the rear door after getting fed up watching drivers obviouly not seeing the standard brake lights, again as its LED its flat and only needs a small hole for the wire.
