How do you replace brake light on Nissan Primera P12?

The saloon version is to open the hatchback. On the inner sides of the the lights is a plastic cover strip which is clipped in place( hidden). Remove this cover strip carefully as the plastic is hard and breaks. You will then find under the light unit the bolts to remove the whole light unit. The unit plugs into the the car wiring and can be unplugged, the screws on the back of the light unit can then be removed to access the bulbs. Best of luck
