Oops! I figured it out...sorry for the post. They're from a 1940 Chevy coupe. Still...they're gonna make cool dual bike lights when I'm done. There's screws in the top side so I think someone may have had them on a bike before.
I picked one of those up at a catch all Swap meet, I thought they were cab lights for a old truck. Not Sure . I sold mine to a friend at Scott’s swap meet in Texas, he thought they were cool also , he was going to put them on his rat rod
