horizontal traffic light

Traffic lights are essential devices that help ensure the safe movement of vehicles and pedestrians on roads. They use red, yellow, and green lights to signal stop, caution, and go.

Horizontal traffic lights are a common sight in Western countries, such as the United States and Europe. They are arranged horizontally so that drivers can easily see them from a distance.

The first traffic signal was installed in London, England, in 1868. It was a manually operated gaslight. Modern electric traffic lights were first introduced in Cleveland, Ohio, in 1914, and subsequently spread worldwide.

Horizontal traffic lights are particularly favored in areas with strong winds, as they offer less wind resistance than vertical ones. They also occupy a wider visual area, making them more noticeable to drivers.
