Diamond Vision flood beam CRT's. Predecessors to today's bright RGB LED's in large display signs. They differ from the CRT tubes used in old monitors by being small, and having a nonfocused electron beam “flood” spraying onto single color phosphor. Diamond Vision once had a rooftop sign near Times Sq. at 47th@7th, but large LED signs have now taken completely over.

My own BetaBrite Prism (from Amazon, for an amazing $69; when it's worth about $300 new!) showing off the colors (which are distorted by the photography), and how it can be used for transit. I have been putting it in the window with holiday messages for the past few years.
Not NYC Deskeys, but train set models. They do resemble what Baltimore had on its highways decades ago. I called them "gas station lights", as shorter versions were common on service stations everywhere. Both Harlem and Hollywood had poles with longer fluorescent luminaires like that, in the past.
