Clock, horn, or light?

The speed of sound AND crowd noise. Both impact the perception of when the horn actually sounded where the light and clock are unaffected by the environment.

The light is the most easily used since it is binary...on or off, nothing between, especially if they're LED based lights that illuminate nearly instantaneosuly.

The timing of hearing the horn depends on where the horn is physically located. It could differ by one or two tenths depending where you are in relation to the horn.

As others mentioned, sound is also not available on the replays.

If it were available, I'm not sure it would be conclusive. When you're looking at a slow-motion replay, frame by frame, it's relatively easy to see when the light is on or off. But, when slowed down considerably, it is difficult to identify sounds. If you could completely isolate the sound of the horn, that would be one thing. But to try and pick it out of the background noise when reviewing video at low speed would be, I think, nearly impossible.
