I remember coming across one of these lights at a scrap yard years ago, before I really got into signal collecting.
Having no idea what it was as I've never seen one before, I picked it up for a closer look. Looking back I realize that it was in great condition, but at the time I was thinking "Yuck! What a strange looking blaspheme of a traffic light!"
I literally tossed it way back into the pile of city junk and kept on digging.
Do we have a "smile" emoticon of someone kicking themselves?
