Elton internal light bar for banjos -- Came from a Paramount

Description

I have seen these on several banjos that I have owned. I originally thought that they were installed as some sort of stage gimmick -- flashing lights or something like that. Eventually someone told me that their purpose was to keep skin heads dried out in damp climates. This is in good used condition. The wiring is gone but I don't think that it will be difficult to re-wire them.  The mounting hardware looks homemade.
