A neon lamp fires @65vac, it might respond to phantom (capacitively coupled) voltages.
A 100w lamp tests for a lamp in series with your wire-under-test & a hair dryer tests for connection integrity, but with these you need clip leads, pin jacks & a soldering iron.
Did you know that the whole PoCo in some cases can be pretty accurately reduced to a 120v source in series with a half ohm resistor?
