My car is an '88 so it has a reverse light in the cluster and requires a fog light for MOT. 

 

 

I really love these reverse lamps:

I know they're not in keeping with the period of the car, but that's not the aim of this build, the aim is just whatever I like. I dislike having a fog light hanging from the bumper (like in the pic above), could I simply fit a red bulb in the spot and use it as a fog? Or would it need a white bulb and red lens? I've read the MOT regs and it seems pretty lenient...

I came across a "U tube" somewhere, where a guy was putting a 'red diode cluster' in the reflector part.  On a Mini, that would be between the Flasher and the Rear / Brake light.

 

I didn't watch long enough to find out the car, nor any snags.

So long as the fog light bulb is of a suitable wattage to be brighter than the brake light this should not be a problem. You get very bright LED style bulbs that should fit in but I suppose it depends on the unit bulb fitment..

Are there any specific requirements for the reversing light, e-mark, brightness etc?

typically ranges from 35 watts for basic fog lights to 100 watts or more for higher-performance models. A higher wattage output produces a brighter, more penetrating beam.

Sorry, I’ll rephrase my question … what are the legal requirements for the reversing light?

The IVA manual is a handy guide to what is legal.

 

You can't put a fog light in the standard rear cluster it won't be far enough away from the stop-tail. Reverse lights are limited to 21w, same as brake & fog. That's a "work light" in the piccy  ;-) (as long as its not switched by selecting reverse.)
