Old Trailer Light Replacements

[SweetLou]

I have an old '66 fiberglass enclosed trailer. It has round taillights which insert like a cupholder with metal component and a snap ring. When going down bumpy road the ground gives out and being fiberglass isn't always easy to get a good ground. Does anyone know of a replacement either original or something newer?

There is two styles. Here ia a replacement assembly which needs to have screws to hold it in.Round tailight This one has the ring retainer.
Other varieties have a rubber grommet to hold them in. Some have a groove to hold into the fiberglass or metal bodies.
Does yours have any identifying numbers on the lens?
