Runway edge lights change color to yellow in the last 2000 feet (FAA) or 600m for EASA/ICAO. Additionally, on an FAA runway the far end of the first set of of the two double-striped distance markers painted on the surface of a precision runway (on either side of the centerline) would indicate 2000 feet remaining. ICAO runways should only have one set of double striped touchdown zone markings and the ends of these markers closest to the far end of the runway indicates 600 m remain. EASA runways only have solid distance markings in which case the touchdown markings just prior to the thick 400m aiming point markers would indicate 2000ft/600m remaining.
