Taxiway intersection lighting consists of how many blue lights placed where?

• A. Two blue lights placed at the taxiway intersection.
• B. One blue beacon at the intersection.
• C. Three blue beacons at the intersection.
• D. A row of blue lights along the taxiway.

Answer: (A)

Blue lighting marks taxiways, not runways. At a taxiway intersection, two blue lights are placed on the far side of the crossing to clearly indicate the intersection itself. This gives pilots a precise cue that they are at or approaching where another taxiway joins, aiding safe and coordinated taxiing, especially in low visibility or at night. A single blue beacon or a row of blue lights would not provide the same specific signal about the intersection, so two lights at the intersection is the standard arrangement.
