What is the color of runway edge lights?

Runway edge lights are designed to provide pilots with clear visual indications of the runway's boundaries during nighttime or low-visibility conditions. The correct color of runway edge lights is white, which illuminates the edges of the runway and helps pilots align their approach when landing and taking off.

These white lights are typically spaced along the sides of the runway and are particularly important for enhancing safety by delineating the runway from surrounding areas, especially in dim lighting conditions. The standardization of these colors is critical for uniformity and recognition across different airports globally, creating a consistent visual cue for pilots during operations.

In contrast, other colors like red, blue, and green are associated with different types of lighting on an airport. For instance, red lights might indicate the end of a runway or a caution area, while blue lights are commonly used for taxiway edge lighting, and green lights typically signify the approach lighting systems or runway threshold. Understanding these distinctions is vital for pilots to interpret the airport's lighting system accurately.
