Help you electronic gurus ...

1) The type of wall switches with a neon lamp which glows when the switch
is OFF (handy for finding the switch at night) can also be used to "test" to
see if there is a load on the other end.

2) It is downright silly to use a delicate and limited life lamp for an
HEATER. Do it right the first time and BUY and install "pump house
heaters" which automatically come on when the temperature gets below 40F or
so.

The best way of protecting pipes is with the special heat tape that turns
itself off as it gets warm.

But LAMPS?

You have to be kidding!
