Runway lights are essential for guiding aircraft during takeoff and landing, especially in low visibility conditions. These lights are strategically placed along the edges and center of the runway to help pilots see the runway's layout and orientation. They come in various colors, with white lights marking the runway edges and red lights indicating the end of the runway. In addition to edge lights, there are also approach lights that extend into the airspace before the runway. These lights help pilots align their aircraft for a safe landing. Overall, runway lights play a crucial role in ensuring the safety of both pilots and passengers.
