1. An apparatus comprising:

  • a means to interface to an external circuit;

    a means to store energy;

    a means to reduce the voltage received from the external circuit;

    a means to convert alternating current from the external circuit to direct current;

    a means to replenish the store of energy with energy received from the external circuit;

    a means to detect the absence of power in the external circuit;

    a means to detect the state of a switch in the external circuit, in which the means to detect the state of the switch comprises;

    a means to randomly generate an outgoing signal, wherein the outgoing signal is imparted with a sufficiently random form that it would be distinguishable from a signal of external origin, and would thereby be uniquely attributable to the apparatus;

    a means to detect a first incoming signal; and

    a means to determine whether the first incoming signal matches the outgoing signal,a secondary light source driven by the stored energy;

    a means to activate the secondary light source only in the event that both an absence of power in the external circuit is detected and a closed state of the switch is detected.
