You can see it the whole time. It has a very interesting refractor, and the top looks unusual, too.

It almost looks to me, like it's on a GE 201SA NEMA head.

The Nema tag looks yellow, It's probably 100w HPS.

Yeah it probably is. When I posted this I didn't know that 100w MV wasn't really used outside of the northeast. Milwaukee still has a lot of HPS streetlights, and a few years ago I saw some LPS ones too. I don't know if they are still there, though.
