Vintage Truck/Car Stop Light With Glass Lense & Bracket

A Vintage 'Truck or Car' Stop Light with a glass lense and the license plate bracket in very good cond. The lense is red glass with yellow 'STOP' at the top and a clear glass lense for the license plate light. The light measures approx. 4" in Diameter x 3"Deep, does show some light surface rusting, some tiny dents and dings and has been painted 2 or 3 different colors. I took the front piece off to clean the lense and saw that the lense is either cracked or been repaired along the very edge. The crack cannot be seen with the cover on and is hard to see with the cover off. T is a socket in the back with a metal covered piece of wire that turns in the socket. T is an old bulb in the socket, but the wires have been cut off. The license plate bracket shows some surface rusting and a couple of small cracks in the metal. This is a very nice Vintage Truck or Car collectible that has to be at least 50-60 years old ( see pictures ). T are NO markings on the light or lense that I can see. Question or input welcome!
