When holding all kinds of competitions and group activities in the billiard room, in order to enhance the distinction between teams and the appreciation of the competition, and at the same time facilitate the audience and staff to clearly identify the situation of different teams, a special indicator light for identifying teams is particularly important. The existing billiard room often lacks such targeted indicator equipment, resulting in insufficient team recognition during the game, and on-site order management and atmosphere creation are also affected to a certain extent. Based on this, we designed this billiard room team indicator to add more professionalism and interest to billiard events and team activities.
