Since I have no idea where a fuse is located, I'd kill two birds with one stone and check power at the switch next. Maybe someone knows the fuse location.

Those fogs are probably run from a relay between the switch and the lights, so that's another suspect - but I'd sure want to check the fuse before tearing everything apart.
