Welcome.

Those look to be just an old pair of cab clearance lights.

Type in "vintage cab clearance lights" (E Bay or Goggle) and you can find a bunch of different variations. The older they are the heavier the metal is and a lot of times they will have real glass lenses. Newer ones will sometimes be made of stainless or aluminum. One thing you want to watch for is that some have a slight curve to the base which will not work well on a flat frame rail.
