How many traffic lights are there in the United States?

Most likely, over a million and I'm just guessing ...
There are over a fifty million. In cities, most intersections have eight or more traffic signals per major intersection. A city as big as L. A. can have 10,000 intersections. Multiply that times eight. Each intersection can have eight or more signal heads. Each head can have 3 to 7 light bulbs.
We are talking some serious numbers. That's not counting pedestrian lights, overhead luminaires, and sign lights.
(not to mention highway overhead lights).
50 million is just a guess but its and educated conservative guess. Pressed for accuracy I would guess higher rather than lower.
