As you already know and see this thing in our prank cursor pack daily on the road, you might forget what it is. These are traffic lights, traffic signals, or stoplights - these signaling devices are positioned at road intersections, pedestrian crossings, and other locations to control the traffic flow. The regular traffic light colors are red, yellow, and green arranged vertically or horizontally in that order. If you see red light, you have to stop immediately. If you see the green light, you can move on.
