Blinking Street Lights
I'm driving home tonight and there were about 8 street lights flashing in unison. These were just your run of the mill HPS street lights that you might see along the road anywhere in America. All 8 flashing on and off together in 1-2 second intervals.
I've never seen anything like it before. Heck, I didn't know a HPS lamp would flash (not that I thought much about it before tonight).
Has anyone seen anything like this before or could offer an explanation?
