What color are taxiway edge lights?

Taxiway edge lights are typically blue. These lights serve an essential purpose in indicating the lateral limits of a taxiway, helping pilots to maintain situational awareness during taxi operations, especially in low visibility conditions. By employing blue lights for taxiways, it creates a clear visual distinction from runway lights, which are usually white, and helps ensure safe navigation on the airport surface. This color coding system is standardized within the aviation community to provide consistency and aid in pilot recognition and safety across different airports.
