Actually, those are the license plate lights on the coupe as well. Both the coupe and the roadster have 2 license plate lights that are just to the left and right of the hatch handle and 1 rear interior light which on the coupe is on the driver side of the trunk area just in front of the taillight access door. On the roadsters, it is on the passenger side on the back plastic rear panel. Those lights are only supposed to be on with the parking lights. Can you check if perhaps they are on with the courtesy lights when you turn the car off? Sorry I couldn't be of more help.
