What color are taxiway edge lights?

Taxiway edge lights are blue in color. These lights are specifically designed to delineate the edges of taxiways, providing visual guidance to pilots during taxiing operations, particularly at night or in low-visibility conditions. The blue color is standardized and easily distinguishable from other airfield lighting, ensuring that pilots can readily identify the boundary of the taxiway.

The other colors associated with specific lighting on airfields serve different purposes: for instance, white lights are typically used for runway edge lights, red lights indicate the edges of runways (or may show caution for pilots approaching a threshold), and green lights are used for runway centerline lights. Understanding the color coding of airport lighting is crucial for pilots, as it aids in safe ground navigation.
