My panel came with two bilge pump breakers and two red lights, each wired to come on when its bilge pump comes on. I didn't see the need for the "on" lights, since I can hear the bilge pumps running.

I rewired it so that, if the breaker is tripped (or shut off) and the float switch tries to turn on the pump, then the red light comes on, as a warning that the pump should be working and is not.

I think that it is a good idea to use an unbroken piece of wire, soldered to the bilge pump and waterproofed, all the way back to the breaker in the panel.
