After landing, when do the runway edge lights turn from white to yellow?

The runway edge lights change from white to yellow when there are 2000 feet of remaining runway available. This change serves as a visual cue to pilots indicating that they are approaching the end of the runway. It is a crucial element of runway safety, helping pilots to make informed decisions regarding their landing and associated operations, such as potential go-arounds or taxiing.

This transition assists in enhancing situational awareness, especially at airports where runways may be close to the airport boundaries or other obstacles. Recognizing the distance left to stop or maneuver effectively is essential for maintaining operational safety on the runway.

The other situations presented, such as entering a taxiway or approaching a VASI, do not specifically trigger this change in light color, and the threshold proximity would not produce the same visual indication as the 2000-foot mark does.
