The colors of traffic lights have a fascinating history! In 1868, John Peak Knight invented the first traffic light in London using gas-powered red and green lights. Later in 1912, the first electric traffic light was invented in Salt Lake City, Utah. In 1920, William L. Potts added a yellow light to the mix in Detroit, Michigan. Each color has a meaning: red for danger and stop, yellow for caution and slow down, and green for go!
