Yes, looking into replacing the bulb. It often turns on for a few minutes before going out. Hope it's not a bigger issue. Was going to try swapping the bulbs to see if that fixes this lamp, but ran into the above problem.
Hadn't even considered I might be aftermarket. That would explain not finding any info on this setup. I've only had the car a couple years with next to no info from the previous owners. Pretty sure there was front end damage that was fixed, so wouldn't surprise me that the lamps are aftermarket.
I'm assuming the igniter is the metal box holding in the bulb that I've seen in diagrams and videos. This doesn't seem to exist in my assembly. There was just a thin metal clip that held the bulb in place.
So maybe there is a clip further up the wires. I'll go check it out.
