Hoping somenone can give a pointer to a device
which I'd have thought would be readily available,
but I'm only finding Big Expensive Fullscale setups.

We've got a sump pump in the basement. I'd simply  
like to know when it turns on (there's a "float" switch).

What I'm hoping for is a simple box that takes utility
power on one side, sends feeds out the other, and will light up
when the line side starts pulling current.

I can reroute the power supply to the pump to pass
through the upstairs where we can watch the lamp.

Thanks for any suggestions.

  IF you want to run a 120ac line to where you want the light,
simply connect wires in parallel with the motor and put the bulb on the  
end. This could be done at the motor or in the float switch.

Do you want to run a 120ac wire?

My suggestion is to use something like this this:

Tie up the float switch on the sump pump so it is always activated.

Run the wire to 2 low voltage SPDT or DPDT 12vdc relays. Make sure the  
relays are rated for 30+ amps for long life. Bosch relays used in car  
alarms for ignition cutoff or power window applications work great. Make  
sure you buy them with the wiring harness. Buy extra ones because  
nothing lasts forever. For your power supply, any cheap 12vdc plug in  
power supply will work to activate the relays. Buy a few extra. You can  
find all this real cheap on eBay.

You want to mount all this near your 120vac source, keep it away from  
the pump as far as reasonably possible.

Use one relay to activate the pump.

Use the other relay to activate your remote indicator. I suggest you use  
a 12vdc LED. A blue or red flashing car alarm LED is about $ on ebay.
