Blue lights on traffic lights?

Early nineties, blue lights on a traffic light below the standard green one. Am I crazy? What were they for?

This was in Westchester County, NY. (North of NYC.) The blue light was much the same as the other lights but with a blue lens, hanging below the green light. I never saw one lit. They're not around anymore, and they were always sort of rare, but there were several if my memory isn't failing me.
I find on Google two kinds of references to it - both of them seemingly new things since the internet became mainstream. One is for catching people running red lights, one is for emergency vehicles. The former seems to imply that I would have seen the blue light on at some point, and the latter has a white light attached as well.
I definitely remember childhood conversations about the nature of the blue light, but no one knew what it was for.
