Do Runway Centerline Lights change colors on an instrument runway as the aircraft or vehicle operator proceeds down the runway?

Runway Centerline Lights are designed specifically to assist pilots during low visibility conditions, particularly in instrument flight conditions. As aircraft or vehicle operators approach the runway's end, the centerline lights change from white to red, indicating to the operator that they are nearing the end of the runway. This color transition serves as a critical visual cue, prompting the pilot to prepare for takeoff or landing and making them aware of their position relative to the runway threshold.

The color change from white to red occurs sequentially, emphasizing the proximity to the runway's termination point, while ensuring that operators are aware of their position. Thus, the correct choice reflects the operational functionality of Runway Centerline Lights in providing essential information to enhance safety during runway operations.
