7. Do all goal lights in hockey produce sound effects?
– No, not all goal lights produce sound effects. The inclusion of sound effects depends on the design and preferences of the arena.
Hockey goal lights work by using sensors that detect when the puck crosses the goal line.

Goal lights vary in design and are commonly used in professional hockey leagues, while availability may vary in recreational leagues. In case of malfunction, officials can rely on video replays and their judgment.
