When a pilot observes equal numbers of red and white lights on a Visual Approach Slope Indicator (VASI), it indicates that the aircraft is on a perfect approach path for landing. The VASI system is designed to provide visual guidance to pilots during approach by displaying red and white lights based on the aircraft's altitude in relation to the optimal glide slope.

When the lights show an equal number of red and white, it means the pilot is at the correct angle for landing, suggesting that they are aligned properly with the runway and at an appropriate altitude. This is an essential visual cue for ensuring a safe and smooth landing, as any deviation from this indicates either being too high or too low, which could lead to an unsafe landing attempt.
