Alternatively, look in your toolkit that is stored with the space saver spare tyre, there will be a small tool with a hexagonal fitting at one end, this is what you use to remove the bolts on the rear light array's. The bolts are located mid way up the rear pillar either side of the rear windscreen, there are two more bolts located in luggage compartment, there should be a hole in the fabric lining. Once the unit is off, disconnect the fitting for the power, and unscrew all 4 screws, you should then be able to remove the light fittings to replace any dud bulbs. Hope this makes sense
