Thank you for all this information, it sounds like I may be best to look at carbide lamps that I can electrify for safety reasons. I don’t think the tubing is conduit because it is only a 1/4” tubing. The photo of the white car is at the Peterson museum in LA, it has been highly customized and is not original. These cars were made in Detroit for only a few years and I believe the one I have is one of only a handful left. I am looking forward to restoring it. I just ordered new rims from Australia so I can build new wheels.
