Croton's Dummy Light is a historic traffic signal located in Croton-on-Hudson, New York. It is one of the oldest surviving traffic lights in the United States and a rare example of early traffic control devices. Unlike modern traffic lights, the Dummy Light consists of a single metal post with a small, boxy signal on top, originally designed to be placed in the middle of intersections to direct traffic.
Installed in the early 20th century, the Dummy Light served as a simple yet effective means of regulating vehicles and pedestrians before the widespread adoption of overhead traffic signals. Its distinctive design and historical significance have made it a local landmark, preserved as a reminder of early traffic engineering. Today, while no longer in active use for traffic control, the Dummy Light remains an interesting piece of transportation history and a point of curiosity for visitors and residents of Croton-on-Hudson.
