Reminds me of the headlight reflectors on the 49 Cadillac, where you could remove bulb and use reflector in house or garage with a regular drop cord. You just put bulb into reflector, then screwed bulb into drop cord. Great inside lighting.OK thanks thats what it looked like to me.
Quite a complicated headlight compared to the 05.
05 on the right minus lens and bulb
06 on the left with turning motor,lens and bulb
