'05 111R fog light not working

[An Marcach]

I've just realise that the rear fog light on my car has stopped working



I'd had been working fine and doesn't any more.

The little indicator light on the switch won't even come on.

I've checked and it's not the bulb and it's not the fuse.

Anyone got any ideas as to where I should start looking before I tear the whole thing apart only to find out if I'd asked it'd have been an easy fix

Yip, all plugged in
