What color is used for taxiway edge lights?

Taxiway edge lights are designed with a specific color to aid pilots in navigating airport taxiways safely. The correct color for taxiway edge lights is blue. This blue color serves as a clear visual indication that differentiates taxiways from runways and other areas of the airport. It helps pilots to maintain situational awareness during taxi operations, especially in low visibility conditions or at night. Each color in aviation lighting serves a distinct purpose, and blue is universally recognized in aviation as the color that marks the borders of taxiway paths.

In contrast, other colors such as red and white are typically reserved for runway edge lights and other specific functions. Yellow, on the other hand, is used for markings indicating caution or for the centerline of taxiways but not for the edge lights. Understanding these color codes is essential for pilots to ensure safe and effective taxiing operations around an airport.
