Very easy:
look inside your boot and remove the plastic cover behind your tail light, it just clips on and off. Put your hand into the opening and locate two plastic wingnuts - one at the top and one at the bottom, remove these and then the whole tail light unit can be removed from the car from the outside. Replace bulb and return unit in reverse sequence easy once you know how. It only takes about 5 mins.
