What visual signal indicates a successful lift?

The visual signal that indicates a successful lift is represented by two or more referees raising white lights. In powerlifting competitions, the lighting system is a standardized method used to communicate the judges' decisions to the lifter and audience. Each referee has the ability to activate a light, and when the lift is deemed successful, the referees will raise their white lights, signaling that the lift meets the necessary criteria established by the International Powerlifting Federation (IPF).

This method of signaling provides a clear and immediate indication of the lift's success, which is crucial in a competitive environment. The use of white lights allows for uniformity and reduces potential confusion among spectators and athletes alike. Other choices, like audience clapping or referees waving their arms, do not convey the official communication required in this context. While head nods may indicate agreement among referees, they lack the formal clarity of the light system.
