I've just carried out this task. Remove the two bolts from the light cluster as illustrated in the owner's handbook. The light cluster is then being held in by a plastic fixing pin on the other side about half way down the light cluster. I put a screwdriver in one side and fingers the other side and gently tugged - this pulled the fixing pin free from the car. You then need to unclip the plastic plate that holds all the bulbs in place - this clip is at the bottom, then you have access to all the bulbs.
