How can one identify taxiway edge lights at night?

Taxiway edge lights are specifically designed to assist pilots in navigating taxiways at night or in low-visibility conditions. The proper identification of these lights is crucial for safe movement around the airport.

The correct identification of taxiway edge lights is that they are illuminated in blue. This blue color provides a distinct visual cue to pilots, clearly differentiating taxiways from runways and providing guidance for movement along the taxiway. The use of blue lights is a standard convention in aviation, ensuring consistency and clarity for pilots navigating the airfield.

Other colors mentioned in the choices serve different purposes. For instance, red lights typically signal a stop or danger in aviation settings, while green lights are commonly used to indicate runway thresholds or approach lighting. Yellow lights are often associated with caution or transitional areas in various contexts but do not represent taxiway edges. The consistent use of blue lights for taxiways helps avoid confusion and enhances safety during ground operations at airports.
