Amber runway edge lights indicate which distance of the runway?

Amber runway edge lights indicate the last 2000 feet of the runway. These lights serve as a visual cue for pilots, particularly during night operations or low visibility conditions, indicating that they are approaching the end of the usable runway. This is particularly critical for pilots during landing when they need to understand their positioning relative to the runway's end to ensure a safe stop. The amber coloration helps distinguish this segment from the rest of the runway, which features white lights for the other portions. Understanding this detail is essential for safely managing runway operations and ensuring compliance with aviation protocols.
