Open the tailgate remove the two screws you can see holding in the light unit. Next there is a flap of carpet inside the boot fold this back and inside this there is a plastic winder which you need too unwind a few turns. Then pull the light unit at the top until it pops out and slide up and out gently. Unclip the wires to free the light unit from the car. Now simply undo the six clips on the back of the light unit to expose the bulbs. Remove the faulty bulb and replace the put back together in reverse order to what you have just done.
