=== Traffic signal ===
{{Main|History of traffic lights}}

Following the success of his company, Morgan became a well-known citizen in Cleveland and achieved financial success leading to his purchasing of a new automobile. In 1922, he witnessed an accident between a horse-drawn carriage and a car which sparked inspiration to prevent future accidents. Morgan designed a manually-operated traffic signal with moving arms featuring "stop" and "go" signs, which could be placed on a post at traffic intersections. The arms could be raised halfway to indicate caution moving forward. A traffic attendant would crank the post to operate the signal and all lanes could be stopped by showing "stop" if needed.<ref name=":0" /> In 1923, Morgan patented his traffic signal. He later sold the rights to General Electric for $40,000.<ref>{{Cite book |last=Brown |first=David E. |title=Inventing modern America: from the microwave to the mouse |publisher=[[MIT Press]] |year=2002 |isbn=978-0-262-26936-0 |location=Cambridge, MA |pages=106–107 |language=English}}</ref>
