I got links too. Garrett Morgan invented and patented the traffic light and gas mask.

The first automated traffic system was shite and caused alot of wrecks because it didn't have 3 signals. The infamous Yellow signal that we still use today is a black mans invention. As well as many other things

He got a patent on a T shaped traffic signal ,not inventing the 3 current color signals nor the myriad configurations used. Also the Brits have something to say about the gas mask.
