Traffic lights are important because they regulate traffic safely and make movement of traffic smoother and faster at intersections.

Without it we would have to use candles that light the room dimly.
You can tell how big a star is using light and you can tell what elements it is made from using light.
A traffic signal is controlled by a control box on the side of the intersection, the control box receives data from electromagnetic sensors under the pavement, and that data is processed by amplifiers inside of the box and the traffic controller makes the appropriate decision on what to do. So to answer the question, the traffic light is a decision made by the traffic controller which is a output.

Yes, you can proceed through an intersection when the traffic light turns yellow, but you should do so with caution and be prepared to stop if it is safe to do so.

The blinking green light in Canada signifies that a driver can turn left at a traffic light intersection when it is safe to do so, even when the light is red. This is a unique traffic signal used in some Canadian cities to improve traffic flow and reduce congestion.
