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. ;-)


Getting a lot rarer than it used to be as most vehicles seem them to turn
them off to a greater or lesser extent, some by a mechanical action that
turning off the stalk headlight switch also turns off the the fog lamp ring
switch others with a more sophisticated method within the vehicles
electronics
after headlights are turned off or the vehicle parked up.

Was that as a result of legislation or just good practice by manufacturers?

It has certainly cut down on those who could justify their use in morning
November fog
but still displayed them on the way home in a dark drizzle annoying those
behind .
