Power Functions (abbreviated as PF) is a system of electronic components, including motors, lights, remote control units and receivers or different power units. These parts can be connected by cables with brick-shaped connectors. The system is the successor to the 9V system and was first released in June 2007, in the sets 4957 Ferris Wheel, 4958 Monster Dino and 8275 Motorized Bulldozer. Some standalone light bricks, sound bricks, and motor bricks were labeled Power Functions on the box of some sets even though they don't interface with the Power Functions system. The system was retired in 2018 and replaced with the Powered Up system.
