What color lights indicate the last 2000 feet of a runway?

The last 2000 feet of a runway are indicated by white lights. This is part of the standard lighting system for runways, where white lights are used to denote the usable length of the runway for landing and takeoff operations. The white lights provide clear visibility and help pilots gauge their position relative to the runway as they approach.

In contrast, other colors serve different purposes; for instance, blue lights typically outline the edges of the runway and taxiway, while amber lights are often used for caution areas such as runway thresholds. Red lights are often used to indicate areas that should not be entered or to signal alerts. Understanding the specific color coding of runway lights is crucial for pilots during night operations or low-visibility conditions, ensuring safe and effective navigation on the ground and during approach.
