Runway edge lights are are white—except on instrument runways where yellow replaces white on the last 2000 feet or the last half of the runway length (whichever is less) to form a caution zone for landings.

RWSL (Runway Status Light System) is a fully automated system that provides runway status to pilots and surface vehicle operators to indicate clearly when it is unsafe to enter, cross, or take off from a runway. The system processes information from surveillance systems and illuminates Runway Entrance Lights (REL) and Takeoff Hold Lights (THL) in accordance with the motion of the detected traffic. The status lights have two states: ON (lights are illuminated red) and OFF (lights are not illuminated).

Rotating beacons

Lighted Land Airport (White/Green); Lighted Water Airport (White/Yellow); Military Airport (2 White/Green). In Class B, Class C, Class D, and class E surface areas, operation of the airport beacon during the hours of daylight often indicates that the ground visibility is less than 3 miles and/or the ceiling is less than 1000 feet. ATC clearance in accordance with 14 CFR part 91 is required for landing, take off and flight in the traffic pattern. Pilots should not rely solely on the operation of the airport beacon to indicate if weather conditions are IFR or VFR. There is no regulatory requirement for daylight operation and it is the pilot's responsibility to comply with proper preflight planning as required by 14 CFR part 91.
