If a traffic light breaks most cities will assign a traffic cop to regulate traffic until the light can be fixed.
The first traffic light was installed in London in 1868, but was gas powered. In the 1890's, electric lights were introduced.

Its most customary meaning is 'signal light' or 'traffic light' such as those typically found at the corner of busy intersections in cities. However, it can also mean a flashing light communications system, or a communications system that uses flags.
The opposite would be "light traffic".
An open loop traffic signal just cycles on a schedule and has no "knowledge" of traffic patterns or current traffic. A closed loop system would have sensors letting it know when traffic was present and a controller that would make decisions based on the traffic conditions.
