I drove through the light on Monday... and there was no light! Duh... where did it go?! It used to be in front of the Lucent Technologies Industrial park. I think it is now Alcatel. At any rate, it is gone. And the light just beyond that was a new light fixture. They must have done it over the weekend. It was quite surprising.
Turns out (and had I thought this through more I'd have known this) the Alcatel there was closed. The light was a timed monstrosity to let the commuters out. But there've been no commuters for a year or so now.
Still, it was very weird!
