Taxiway lighting refers to the illumination systems installed along airport taxiways, which are the paths aircraft use to move between runways and terminals. These lights help pilots navigate safely during low visibility conditions, such as at night or in fog. The lighting typically includes edge lights, which outline the taxiway, and centerline lights, which guide pilots along the center of the path. Proper functioning of taxiway lighting is crucial for maintaining safety and efficiency in airport operations, ensuring that aircraft can taxi without confusion or risk of accidents.
