If you REALLY want glitzy.. take two count up timers.. one across the pump
motor, and one on the current relay sensing the motor.. if the timers display
two different times, then the pump is being called for, but not running
for the "number of hours difference between the two timers".

Then you don't have to sit up watching for the led.. just compare the
timers every so often...
