After landing, what does the runway edge lights changing from white to yellow indicate?

The transition of runway edge lights from white to yellow indicates that an aircraft is approaching the last 2,000 feet of the runway. This visual cue is crucial for pilots, as it provides an alert that they are nearing the end of the usable runway length. It assists them in making necessary preparations for landing or for initiating a go-around if the landing is not satisfactory. Understanding this signaling helps pilots to better gauge their landing performance and take appropriate actions to ensure a safe landing process.

The other options do not align with the standard runway lighting conventions, making them incorrect in this context.
