Somewhere on this forum it is written that the 3rd brake light on the roadster is held on by five screws. I just removed mine and there are SIX screws. There is a screw on the right-center side (looking rear forward) that is hidden behind a piece of support metal. After you remove all the screws you will have to carefully pry the third light up as there are some plastic pieces and the plug remaining. These must come straight out.
