2004 Lesabre limited. I need to replace the one of the rear marker lights located on the TRUNK LID between the reverse and brake lights. I know the entire 8 nut assembly has to come off but I want to make sure I have the correct bulb before taking it apart.

what are those bulbs or at least what would they would be called? looking up parking/marker lights in a catalog shows just the multi brake/directional marker lights for the end.
