I have had some lights for many years and supposedly they came off a couple old Cadillac Ambulances. They have cast aluminum housings with stainless retainer rings with some red lights, some clear sealed beam bulbs. Looks like they came off of the front and rear of curved roofs, with one set a little longer than the other. I would like to id them to help find someone that needs them along with some other stuff that was stripped off them before they were hauled off back in the 70's. If they go to a swap meet, they will wind up on a rat rod. Any help for an era and manufacturer would be appreciated. The forum wouldn't let me upload them.
