Actually the very first traffic signal was located in London in 1868 but they were gas. In 1910 a non-illuminated sign was invented but the first electric traffic signal was invented in 1912. There were a few others invented between 1912 and 1923 when Garrett Morgan patented an electric automatic traffic signal in 1923.
