Is it OK for rear fog lights to go off when the ignition is turned
off?....

Anyone ever fully understood why we only have one high intensity rear
fog lamp?

some very old buses have ONE rear light and it is still legal to have
them on the road and it is not an MOT failure....

I understand that rules for old vehicles are different, but on a vehicle
which otherwise has a full set of lights on both sides, it seems odd to
allow a single HIRF.

I agree. The lighting regulations baffle me: they allow a single rear fog
light and yet you can be prosecuted for having a "single" tail light (due
to a bulb failure). And they allow indicators which are very close to (and
therefore masked by) headlights or brake lights. Some VW Golfs are guilty
of the rear indicator which is almost invisible when the driver brakes.
Almost every car made in the last 30 years has its front indicators in the
same housing as the headlights and so very hard to see at night on an
oncoming car.

There is something unusual about your eyes. I dont get that effect with
the indicator being invisible when braking or being dazzled by people
stopped at the lights etc at night with their foot on the brake pedal
either.

Tho I spose you can make a case that car lights should be designed so
that those with eyes like yours dont have a problem. Hard to see how
to do that with the brake lights when stopped at night at the lights tho.
