The history of the traffic light starts with a manual version of traffic signaling that was first used in London in 1868, but its two signal arms were manually manipulated by a lever instead of being operated through electricity.
Commemorating the installation of the first electric traffic signal system in the United States, International Traffic Light Day dates back to August 5, 1914 in Cleveland, Ohio.
The system was designed by a policeman named Lester Wire, from Salt Lake City, Utah. Only ten years after this remarkable achievement in Cleveland, the first electric traffic light system in Europe was installed in Berlin, Germany.
That first traffic light signal only had two colors but just a few years later, in 1923, the three color signal light was invented bringing the yellow “caution” light into play. International Traffic Light Day offers an ideal opportunity to celebrate this interesting anniversary.
