Blue and green taxiway lights help pilots navigate safely on the ground. Blue lights usually outline the edges of taxiways, while green lights identify the taxiway centerline that aircraft should follow during taxi operations.
This visual separation is especially important at night, in poor weather or at complex airports where multiple taxiways, aprons and runway entries intersect.
Taxiway lighting may also work together with red stop bars, yellow runway guard lights, illuminated signs and control systems to reduce runway incursion risk. At controlled airports, these systems are typically managed by the tower through an Airfield Lighting Control and Monitoring System.
