The invention of the traffic light is credited to Garrett Morgan, an African American inventor and entrepreneur. In 1923, Morgan patented his version of the traffic signal, which featured a three-positional beacon that used a manual control. This design helped improve traffic safety by providing clear signals for when vehicles should stop, go, or proceed with caution.

Morgan's invention was particularly significant at a time when traffic accidents were increasing as a result of the growing number of cars on the road. His innovation in traffic management not only improved road safety but also paved the way for advancements in transportation systems that continue to impact society today.

Garrett Morgan's contributions to traffic control have had a lasting legacy, highlighting the importance of Black inventors in shaping the modern world.
