US Version

In order to stop the machine, you need to press these buttons to shut down power. The lights on top show which circuits are still receiving power. When you press a button, it will switch the state of the light it's connected to, as well as any adjacent lights, so lights that are on will go off and vice versa.

Quick! Work out which button controls each light, and turn them all off.
