AC Current Indicator Light Circuit
designed by David Johnson, P.E.

This circuit could be wired into a 120vac power line, which feeds power to any load, ranging from 40 watts to 250 watts.  It will turn on a LED light whenever current is being drawn by a load.
It is especially useful for remote lights, where you may not be able to see if the lamps are receiving power.
