One of the brake lights on my '05 roadster has gone out. Looking into the trunk it seems to me that in order to access the screws holding the tail-light housing it's necessary to remove the entire trunk lining, including the center plastic cover. Surely it can't have been that poorly designed. In the interior, just above the housing is a small plastic screw which is easily removed, but the rest of the lining seems to be secured with plastic "buttons" which I'm afraid to start yanking on for fear of breaking something. Am I missing something obvious which makes it easier to replace a simple brake light?
