A circuit for controlling a plurality of light-emitting devices disposed on an object in a sequence includes a water-proof enclosure embedded in the object, a motion actuated switch, a controller, and a battery. The motion actuated switch is mounted within the enclosure, for triggering the controller in response to a motion of the object. Moreover, the controller is mounted within the enclosure, and electrically connected to the motion actuated switch and electrically connected to the light-emitting devices respectively, for driving the light-emitting devices lighting in a predetermined way when triggered by the motion actuated switch. Furthermore, the battery is mounted within the enclosure, for supplying the circuit with electrical power.
