I just want to make sure that you know that the trunk light is mounted ON THE TRUNK LID on the 92s, not in the trunk. The light is located just to the right of the power trunk release solonoid. It lights up the trunk quite well (until you lean in front of it to get something). I am tempted to get one of this style to augment the dual trunk lights in my trunk.
I don't mean to discourage you from getting the 96 style lights, they're really nice too, but I wanted you to check yours, it might just be burned out.
