1. Apparatus for monitoring the voltage applied to an electrical appliance and for visually signalling a drop in said voltage below a predetermined acceptable threshold to a location remote from said appliance comprising, in combination:

  • (a) means electrically coupled to a voltage supply for said appliance for sensing when the amplitude of the voltage from said voltage supply has fallen below said predetermined acceptable threshold;

    (b) a power source independent and electrically isolated from said appliance voltage supply; and

    (c) xenon flash lamp means operatively coupled to said means for sensing and to said independent power source for providing an intense flash of light visible at great distances at predetermined intervals, so long as the amplitude of the voltage of said voltage supply remains below said predetermined acceptable threshold.
