During the pregame warm-up, the officials observe that the facility has functioning LED lights on each backboard. A1 begins the act of shooting just prior to the expiration of time in the first quarter. The covering official observes the attempt in A1’s hands when the LED light is activated, but the ball appears to be out of the hands when the horn is sounded. The ball goes in the basket.
No goal; the quarter expired prior to the release of the try. COMMENT: Red/LED lights provide a visual reference for officials to determine when a period has ended. The red/LED lights and the horn are expected to be synchronized ,but since light travels faster than sound, it may appear that one follows the other. The red/LED lights give a more precise indication that a period has expired.
