These fog lights are made by Carello, the folks that make lights for Ferarri and Alfa and Porsche. They are clearly old. I've surfed the web for days and can't find any that look like these. I'm thinking they may have been for a factory application since they are an unusual size. They are also very heavy with thick metal housings and very thick mounting brackets. Someone suggested a late 50's car. Has anyone ever seen any like these?
They are after market accessary back up lights, Hella made very similar ones and they appeared on VWs and Porches.
