traffic lights

Traffic lights, also known as traffic signals or stoplights, are devices used to control the flow of traffic at intersections. They typically consist of three colored lights: red, amber/yellow, and green. The red light signifies "Stop," the amber/yellow light serves as a warning of an impending stop, and the green light indicates "Go." Traffic lights follow a standard sequence of operation: green, amber/yellow, red, to manage traffic safely.
