What is the color of intersection taxiway and apron lights?

The color of intersection taxiway and apron lights is yellow. Yellow lights are specifically used in airport operations to signify caution in areas where taxiways intersect with aprons. This is particularly important as it alerts pilots to the potential for obstacles or increased traffic, helping to ensure safe movement on the ground.

Using yellow for intersection taxiway lights helps delineate areas where special attention is needed, as opposed to other colors that may indicate different meanings. For instance, green lights typically indicate taxiways or runways that are clear for use, while red lights indicate restrictions, such as runway holding positions. Thus, knowing that yellow lights serve a distinct purpose at intersections is key for pilots and ground personnel to maintain operational safety at airports.
