There is some dispute as to who really invented traffic lights. Police officer William L Potts is credited with developing the system of lights to control the increasing numbers of automobiles in Detroit, Michigan, but others had similar ideas before him. The world's very first traffic light was operating in London, England, even before the advent of the automobile. Installed at a London intersection in 1868, it was a revolving gas-lit lantern with red and green signals. However, on 2 January 1869, the light exploded, injuring the policeman who was operating it. Actually, the traffic light concept was invented in the early 1900s by Garrett Morgan, an African-American living in Cleveland, Ohio. He was the one who developed the electric automatic traffic light. This was before Potts's first invention was installed in 1920. Originally based on a semaphore-system, traffic lights gradually evolved through the years to become the red-amber-green lights they are today - and this is where Potts's invention had its influence.
