What color lights are commonly used for taxiway edge lights at airports?

Taxiway edge lights at airports are commonly colored blue. This specific color is utilized to safely delineate the edges of the taxiway, guiding pilots during ground operations, especially in low-visibility conditions. The blue lights are clearly visible from the cockpit, helping to avoid confusion with other lights, such as runway lights which may be white or colored differently.

Using blue lights for taxiways serves an essential purpose in airfield operations; it indicates to pilots which areas they can safely taxi on without encroaching on other critical zones such as runways or designated hazards. The adoption of a standardized color for taxiway lights contributes to overall air traffic safety by providing uniformity across different airports.
