More details on the project...
   I am attempting to light remote LEDs when I equipment lights are
energized.  The equipment lights flash much like a turn signal.  I want the
remote LEDs to flash at the same periodicity as the equipment lights.  

So I want to have about 3 LEDs to light and extinguish in sequence with the
flashing equipment lights.  Also I want the transmission/sensing circuit to
be minimally invasive.  On the equipment I have 12V available and could make
a voltage divider for necessary voltages.  

When the lights on equipment are no longer flashing I want the
transmitter/receivers to go to sleep if possible to conserve energy.  Do you
know anything about the ezPIC serial programmer?  

Thanks for the help.
