Vertical traffic lights are commonly seen in Asian countries such as South Korea and Japan. The lights are arranged from top to bottom: red, yellow, and green.
This type of traffic light allows for efficient use of space on narrow roads or in complex urban environments. They are particularly common as pedestrian signals.

The color arrangement of vertical traffic lights is based on scientific reasoning. Red is the most visible color from a distance, which is why it's placed at the top. This is effective even in foggy or inclement weather conditions.
With the widespread adoption of LED traffic lights in modern cities, energy efficiency has greatly improved. In particular, South Korea's smart city projects are incorporating AI-powered intelligent traffic light systems to optimize traffic flow.
