What we have here is an HD piston halogen light connected on two shifter arms wrapped by a stainless steel line. It stands on a Harley-Davidson derby cover with a screaming eagle emblem. A push switch fires it up. Needs an ignition key to turn it on.
Top hubcap logo cut out with piece of blue plastic beneath, lights through. Bottom hubcap is late style. We owned a number of late and early VW's when I was growing up. Pull chain end is late VW key, shaped and milled so chain fits.
