Nah, I'm not worried about shock. I just want a visual
indication in our main living area as to when the
pump kicks on.  

If we don't see it come on at all in umptity hours, then
we'll know to make a trip downatairs...

Is your sensor sensing what you really want to know???
What I'd want to know is if there's water in the basement.
If your motor is "open", not sensing current won't tell you that
it's working.  Or if the hose gets disconnected, running the motor
isn't draining your basement.
And I'd think that it working is not the concern.
Not working is the problem.

A microswitch mounted on an independent float gives you what you really
want to know and actual redundancy.

Make the sense float a little higher than the first and put a buzzer on  
it. No high voltage wiring required.

How about a second battery-backed sump pump mounted higher with a loud  
alarm wired across the motor?

Then if the main pump fails or is overwhelmed by a leak you have both  
an audible warning and some added protection, and you can run the  
(fused) 12V wire upstairs to operate a light and an automotive warning  
chime. I wouldn't put too much of a load upstairs, like a horn,  
because it will cut into the run time if the AC power fails when you  
aren't home.
