If you look at the PCB board in the headlight switch assembly you will see a rubber pad which sits between the fog lamp buttons and the PCB itself.. If you remove it (and you don't need to… pain to get it back in) you would see that there is an LED mounted to the PCB for the front fog light, however there is not one for the rear fog.
Some research would need to be done to figure out the exact led that is being used by BMW on these PCB's… but you could easily solder one on.
