What color are the TWY edge lights?

Taxiway edge lights are designed to help pilots identify the edges of taxiways during low visibility conditions or at night. These lights are specifically colored blue. The blue color is consistent across airports, allowing for standardization and minimizing confusion while navigating taxiways. By ensuring that taxiway edges are visibly marked with blue lights, pilots can more safely maneuver their aircraft on the ground.

In contrast, white lights are generally used for runway edge lights, green lights indicate the beginning of runways, and red lights often denote the stop bars or the edges of runways and taxiways, guiding pilots on where to halt or transition. Recognizing these color-coding conventions is vital for effective airport operations and safety.
