1. A load control device for controlling the amount of power delivered to an electrical load from an AC power source, the load control device comprising:

  • a controllably conductive device adapted to be coupled between the AC power source and the electrical load to control the amount of power delivered to the electrical load, the controllably conductive device having a control input;

    a timing circuit adapted to be coupled between the AC power supply and the lighting load, the timing circuit having an output for providing a timing signal;

    a triggering circuit operatively coupled between the output of the timing circuit and the control input of the controllably conductive device, the triggering circuit operable to conduct a control current in response to the timing signal, the controllably conductive device rendered conductive in response to the control current; and

    a status indicator circuit operable to conduct the control current and provide a status indication in response thereto.
