Taxiway lights are essential visual aids used at airports to guide aircraft along taxiways, which are the paths that connect runways to terminals and other areas. These lights help pilots navigate safely, especially during low visibility conditions, by marking the edges of taxiways and providing directional information. There are different types of taxiway lights, including blue edge lights that outline the taxiway and green centerline lights that indicate the center of the path. Proper functioning of these lights is crucial for maintaining safety and efficiency in airport operations, ensuring that aircraft can move smoothly on the ground.
