I have a Zafira C tourer and wish to remove the upper stop lamp unit The 2nd picture shows the trim removed and it shows two metal looking tabs at either end and in the centre between the two metal tabs there is a small hole. In that there appears to be a small pointed tab end. However I have tried depressing these and nothing happens. Can anyone please advise me how I remove this unit.
