The modern electric traffic light is an American invention.[4] As early as 1912 in Salt Lake City, Utah, policeman Lester Wire set up the first red-green electric traffic lights. On 5 August 1914, the American Traffic Signal Company installed a traffic signal system on the corner of 105th Street and Euclid Avenue in Cleveland, Ohio. Based on the design of James Hoge, it had two colors, red and green, and a buzzer to provide a warning for color changes.Driving in this snow and ice is a pain in the butt.

The first four-way, three-color traffic light was created by police officer William Potts in Detroit in 1920.
