high brakelight worn out

Does anyone know how to remove the high brakelight, ther are two small holes in the rear hatch but I can not see any screws or clips, I need to put in new bulbs......

Open the tailgate, and remove the two plugs from the holes behind the light unit, then remove the screws an remove the light unit from outside the car. Release the retaining clips an withdraw the bulbholder - the bulbs are capless (5 Watt), just pull them out and replace
