Which color lights are used to indicate a runway?

Runway lights are primarily white, which distinguishes them clearly and provides pilots with adequate visual guidance during approach and landing at night or in poor visibility. The use of white lights helps ensure that the edges and centerline of the runway are easily identified, which is critical for safe navigation and operation on the runway.

Green lights are used to indicate the start of the runway, typically positioned at the threshold, and yellow lights are often used for taxiways or to indicate caution areas, thus serving different purposes. Red lights signal stop or danger zones, usually around the end of the runway or in areas where aircraft should not enter.

Understanding the function and designations of these lights is essential for pilots to navigate safely during takeoff and landing, making the identification of white lights as the standard for runway indication vital knowledge in aviation.
