help identifying old light fixture

My dad & 2 brothers operated an Esso station from the 50s on; I only remember specifics from the late 70s on. My dad built a VW based dune buggy in the late 60s & used the light fixtures shown in photos for turn signals/park lights. Everyone has passed on & I restored the car, keeping some of the original appointments like these lights. Curious if anyone can identify what the light fixtures originally came off of. I've asked everyone in local car club, but nobody recognizes them. Thanks.

 

Looks like something from a old Japanese motorcycle

 

Might be clearance light fixtures on semi’s!

 

An earlier version of these? From J C Whitney maybe?
