I did get a message from one of his Gals, that there is no hole in the right light. So maybe no bulb. My guess the reason for the copper strip is it is a subassembly. Possibly automated. Possibly supplied by a subcontractor. So cheaper to have one part number/one process for both.

It does seem very strange that J. Carter says they have "developed " a set of lights. Knowing that folks want two lights so as to have tail and stop/turn......and then not provide that. Very strange. But also hard to believe a whole operation for rivet on bulb holder could be missed at assembly.
