What color are standard runway lights for the last 2,000 feet of runway?

The standard color of runway lights for the last 2,000 feet of a runway is red. This color indicates to pilots that they are approaching the end of the runway, serving as a crucial visual cue during takeoff and landing, especially in low visibility conditions or at night. The use of red lights helps ensure that pilots are aware of their position and can take necessary action if they are approaching the end of the runway.

In contrast, other colors are used for various other purposes in aviation lighting. For instance, blue lights typically mark taxiways, while white lights are used along the length of the runway to indicate the central alignment. Yellow lights are often reserved for specific situations, such as marking certain types of obstructions or taxiway edges. The use of red lights for the last segment of the runway is a standardized practice designed to enhance safety and awareness for pilots during critical phases of flight.
