Origin of 'stoplight'
The term 'stoplight' comes from the function of the device, which instructs drivers to stop at intersections. The word 'stop' indicates the action required by vehicles when the red light is illuminated. 'Light' in this context refers to the illuminated signal of the device. Traffic lights began being developed in the late 19th century, with the first installed traffic light being manually operated and appearing in London in 1868. The automation of traffic lights occurred in the early 20th century with the introduction of electricity. The standard three-color system used today was popularized in the 1920s and has become a critical element of traffic management. Over the years, advancements in technology have led to the development of more sophisticated traffic lights with sensors and timers, enhancing their effectiveness in modern urban environments.
