the goal judge. One goal judge is positioned outside the rink directly behind each goal net. For arenas so equipped, the goal judge turns on a red light behind the goal to signal a score. The red goal light and the adjacent green light are connected to the arena game clock. When the clock operator stops the clock, or the time remaining expires, the red light is not able to be activated. In the NHL, the green light is activated only when the game clock reads 00.0 seconds: in lower levels, the green light may be linked to the scoreboard's siren or turn on whenever the time is stopped. In games governed by the IIHF, goal judges wear the same black-and-white striped shirts as on-ice officials. This is not the case for goal judges in North America for games under different hockey codes: their goal judges are usually dressed in apparel bearing a league or hockey association logo, such as sport coats or athletic jackets. In the mid-2000s, the National Hockey League relocated goal judges to higher locations (most commonly the press box, a catwalk or the lower section of the upper deck) with wireless signals. The idea was to allow teams to sell the prime seats, but also to give officials a better view of the action as to be able to reject goals if violations (illegally kicked in, a player in the crease, offside) took place. However, with the expansion of video replay and the addition of a second referee on the ice, the role of the goal judge became relegated to activating the goal lights. The league ceased using goal judges after the 2018–2019 season. The video goal judge now activates the goal lights from the video replay booth. Goal judges were first used around 1877 in Montreal, and were initially called umpires. Video goal judge The video goal judge reviews replays of disputed goals. As the referee does not have access to television monitors, the video goal judge's decision on disputed goals is taken as final. In the NHL, goals may only be reviewed in the following situations: puck crossing the goal line completely and before time expired, puck in the net prior to goal frame being dislodged, puck being directed into the net by hand or foot, the puck deflected into the net off an official, and the puck deflected into the goal by a
