Help ID tail light bracket. Trailer?

[signsup]

This came in a lot of take off Humvee parts, and presume it has nothing to do with a Humnvee. What little I have worked on WWII trailer, they usually had a bracket similar to this to hang a tail light from. So guessing modernish trailer. Service tag riveted to bracket but no other data. 24 v 4 wire Packard connectors. Must be drivers side due to the service tag placement. I only have the one and certainly don't need it so looking to find a home for it. Any assistance appreciated. This auction estate also had military 2 1/2 t and 5 t trucks but no trailers, so it could be anything.
Thanks in advance.

No idea, but the service tag suggests it was something equipped with air brakes.

OK, thanks for the lead. I'll post something up on the truck forum. Maybe a dump? Something that needs the tail light out on an outrigger?
