All of my back lights seem to have gone out, I have checked the bulbs and the fuses, but cant see anything obvious. Which fuse does the rear lights?
Any Ideas?

Depends which rear lights. If all are out then it is a common fault and maybe an earth return has got chopped or there are multiple faults.

However - Fusebox inside vehicle - fuse 16 and 28 feed the rear tail lamps RH and LH respectively.
