A stoplight is a device that manages how traffic flows on busy streets and highways. Many stoplights are mounted on a pole, and there are also lights that hang on a wire above heavily traveled intersections. We sell stoplight posters that highlight each of these designs. In some areas, most stoplights will blink constantly after a certain time of day or night.
