What color are runway lights?

• A. Blue
• B. White
• C. Green
• D. Red

Answer: (B)

Runway lights are designed to clearly define the usable portion of the surface and guide you along the path for approach, landing, and rollout. The lights that line the runway edges are white, providing a bright, high-contrast outline that’s easy to track in various weather and lighting conditions. On precision instrument runways, the last portion of those edge lights is amber to indicate you’re nearing the end of the usable runway. Keep in mind that other airport lights serve different roles with different colors—blue lights mark taxiways, for example—so the color system overall helps you quickly interpret where you are and what to expect in different phases of taxiing, takeoff, and landing.
