What color are runway edge lights?

Runway edge lights are designed to enhance the visibility of the runway to pilots, particularly during night operations or in conditions of low visibility. The correct color for runway edge lights is white. These lights are installed along the edges of the runway to help define its perimeter and guide aircraft during takeoff and landing.

Having white lights serves not only to mark the runway but also to provide a clear visual reference to pilots, ensuring they can maintain the correct flight path. In certain situations, the color and configuration of runway lights are standardized internationally, thus providing a uniformity that is critical for safety and operational efficiency in aviation.

Other colors such as green, red, or blue serve different purposes in the airport lighting system. For example, green lights typically mark the approach lights for runways, red is often used for the ends of runways or obstructions, and blue lights are associated with taxiways. Understanding the function and classification of these lights is fundamental for safe navigation and ground operations at airports.
