Here is a very cool antique emergency light that likely came off an ambulance. It was purchased out of the estate of a funeral home. It features an all glass red lens that is marked "AP3522-2-R" and "Made in the USA." The lens appears to have originally been intended for use in aviation, such as on a runway. There is a chip in the lens on the bottom, which you can view in the photographs. The light originally had a badge with the maker's name, but the lettering has been worn away. The light has three bolts for mounting on the base. It has not been tested and is being sold as is with no guarantees as to functionality.
