What Is This Map Light For

I got this map light with a bunch of parts that came with my 72 Swinger. I thought it was for an A-Body maybe 67-72 as the 73 and later A-Bodies have the large toggle switch undet the dash frame. The more I look at it I think it is for something else but I am unsure what Mopar it fits.

Any help will be appreciated.
