The first stop light was made in 1914 though other sights say different things. It was made by Garrett Morgan. Garrett Morgan was an African-American inventor. Unfortunatly, sights didn't say what the first one was made of.

History
The stop light is placed on a road and it changes the color so drivers on the road know how fast or slow to go, like green means go fast (or just plain go) and yellow means slow down the light is about to change red which means to STOP, but unfortunatly most people don't pay attention, they are mostly on there phones.
To use it some one has program it to make sure the light changes on time. And hopefuly the people acknowlage the color of the light.
