traffic light
A traffic light (also known as a traffic signal or stoplight) is a signaling device positioned at road intersections, crosswalks, and other locations in order to control the flow of vehicular traffic. Traffic lights consist normally of three light signals of the colors red, yellow, and green/blue arranged vertically or horizontally in that order. While this is standardized internationally, variations may exist.
