What colour are taxiway edge lights?

Taxiway edge lights are specifically designed to assist pilots in identifying the boundaries of taxiways during operations, particularly in low visibility conditions. These lights are colored blue. This distinctive color is important as it helps distinguish taxiway edges from other surface markings and lights, such as those used on runways, which are typically white.

The blue color of taxiway edge lights ensures clear navigation along the taxiways, preventing potential misdirection onto runways or other areas. Therefore, understanding the function and color of taxiway edge lights is crucial for safe airport operations and for vehicle operators who may be navigating the airside areas.
