My neighbour found this...thing and asked me what it was, but I've been unable to identify it.
Here are a couple pictures of said object.
It has a working AM/FM radio. The radio has no output, just built-in speakers. It also has a general label posted on the top (where the pole is coming out) that primarily warns against electrical shock. The label suggests it would be used with a lighting fixture of some sort, as it addresses attaching a lighting fixture to the pole.
I can answer any questions that might help.
