:?: Hi, I have a 2006 Cayman and have a problem with the rear left stop light not working. The message on the computer is also indicating this problem. Could anyone please advise me 1. what the correct wattage bulb is required (is it a single filament or combined tail lamp and stop lamp) and 2. which bulb is in in the light cluster (position of bulb within the cluster) . If I cannot replace it myself I will have to go to the nearest Porsche Center (which could be costly). Many thanks for any advice you can give.
