Yes, the white lens is the light and it does look like a courtesy light, but my doors do not have a cut out for them. I'm thinking that they are for something else. I don't believe they are for the Monaco. I found it in the trunk, probably someone tossed it in.Does the white lens light up and the red lens is a reflector? If so, then I'm guessing it's a courtesy lamp assembly for a front door, mounted in the trim panel.
