DWMWJZZ is 🤯 - Check out the first 3-color traffic light on Michigan Ave. and Woodward Ave. in Detroit 102 years ago!

Detroit traffic officer William Potts created this three-color, four-way traffic signal in 1920. Previous illuminated signals used only red and green lights. In October 1920, his new creation, a three-color traffic signal tower that could be seen from all directions, was installed for the very first time - at the corner of Woodward and Michigan Avenue in Detroit. After the city acknowledged that the new light did indeed cut down the number of accidents, Detroit installed more, making a total of 15 four-way lights.
