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 facilities. 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 edge lights, centerline lights, and stop bar lights. Edge lights are typically blue, while centerline lights are green. Stop bar lights, which are red, indicate when an aircraft must stop before entering a runway. Together, these lights enhance safety and efficiency in airport operations.
