The light was proposed by John Peake Knight, a railroad engineer.
He modeled the traffic control after the system used by the British railroad. An arm was moved up or down by policeman to signal whether traffic should stop or go. The arms could not be seen at night so the signal was changed to using red and green gas lamps.
