What color are the last 1000 feet of runway centerline lights?

The last 1000 feet of runway centerline lights are indeed red. This color serves an important purpose for pilots approaching for landing. The red lights signify that the aircraft is nearing the end of the runway, which can help in determining the margin for safety and ensuring that the aircraft has sufficient distance for landing and stopping.

In addition to marking the last section of the runway, the color coding of runway lights is standardized to enhance situational awareness and improve safety during landing operations. Pilots rely on the visual cues provided by the lights to make informed decisions as they approach the runway.
