What colour are taxiway edge lights on an airside operation?

In airside operations, taxiway edge lights are designed to provide clear visual guidance to pilots as they navigate the taxiways. These lights are blue, which is a specific color used exclusively for taxiway edge lighting.

The purpose of the blue lights is to delineate the edge of the taxiway surface, providing a visual reference, especially during low visibility conditions or nighttime operations. This color helps to ensure that pilots can safely stay on the travel path designated for taxiing aircraft.

Each color of airfield lighting serves a distinct purpose, which is critical for the overall safety and efficiency of airport operations.
