What colors do civil airports typically use for their flashing lights?

Civil airports typically use white and green colors for their flashing lights due to their specific functions in aviation safety and navigation. The white lights are primarily used for runway lighting and approach paths, providing clear visibility for aircraft during landing and takeoff. The green lights are often used to indicate taxiway entrances or to mark the threshold of runways, helping pilots navigate the airport environment safely.

This color combination ensures that pilots can easily identify critical areas of the airport, especially in low visibility conditions, enhancing overall safety. Flashing lights serve as visual signals for pilots, and the standardized use of white and green is recognized internationally, ensuring consistency across civil aviation operations.
