So I have a great idea for some exterior lighting that would use the plastic filler piece on the mirror since I don't have the stock turn signal/puddle lights but I can't for the life of me figure out how to get the little plastic "cup" where the stock puddle/turn signal lights are at off. I can see there is a screw holding it on but I can't get to the screw to release the plastic piece. Any help would be appreciated, I'm ready to roll on this mod I just need this to get started.
