do fog lights and especially rear fog lights require a warning light

They have done since at least the 1961 lighting regulations, possibly
earlier.

Still doesn't stop plenty idiots leaving them on. ;-)

Not necessarily idiots. Many years ago I took my car for an MOT and the
inspector left the foglights on. Driving home, my dipped headlights were
off, so the foglights didn't come on. The next morning, driving to work,
I needed my dipped lights on and did not notice that the foglights were
on for some time - the switch and indicator were positioned badly, so
they were not easily seen anyway and were completely hidden by my right
arm whilst driving.
