So at the Lumber Street crossing in Chicago (which if you ever do come to Chicago, I strongly suggest you visit it on a weekday) they recently installed gates, and a few extra lights. These lights with the black backs are not new, the gates are, but I've never seen lights with the black backs, except with the GRS Plastics. Any idea what these are? There were no logo's anywhere on any of the lights.

I also do plan on submitting these to the site, since I haven't in a long, long time.
