Yeah, those lights on the drivers side can be tricky. They may be called off door side, maybe, or as kdk1220 says, maybe tied in to storage compartment lights, maybe called a road light. "IF" its a big bright light, it might be a spot light, or a scare light, or even security light.
I started with nothing, and still have most of it left
