What do yellow runway edge lights signify?

Yellow runway edge lights indicate that the end of the runway is approaching. This is an essential visual cue for pilots, especially during landing and takeoff phases, as it helps them maintain situational awareness regarding the dimensions and layout of the runway. Knowing where the runway ends allows pilots to make informed decisions about their approach and landing safely.

In contrast, the other options refer to different aspects of navigation and runway usage. For instance, they might involve different types of lights or markings that serve specific functions, such as guiding pilots to taxiways or alerting them to obstacles. However, the function of yellow edge lights specifically centers on signaling proximity to the runway's end.
