Keep in mind, light mfg. sold these type of lights to anyone. In petroleum equipment catalogs they called the service station lights, other industry catalogs would call them something else.
Most of us are familiar with Revere, Rutledge, Goodrich (not the tire company), Phillips and Whiteway. They all made similar type lights.
I have seen this type of light used in drive-in theatres, boat docks and out in front of just about anywhere.
I have catalogs for all the brands listed above, but none of them show a light like yours.
