What color are edge taxiway lights?

Edge taxiway lights are blue. This is a standard color used in aviation to indicate the lateral boundaries of a taxiway. The use of blue lights helps pilots easily identify the taxiway at night or in low visibility conditions, ensuring safe movement on the airport surface.

Green lights are typically used for runway thresholds, while red lights are used to indicate the boundaries of runways or to signify stop conditions. White lights are primarily used for runway centerlines. Understanding the color coding of runway and taxiway lights is essential for pilots to maintain situational awareness and navigate safely around an airport.
