There has been a few questions in the Chat area as to the use of Filament lamps as test equipment.
Personally I don't really agree with the idea.
I'd sooner use a Solenoid like the Duspol N tester:

And it has a Neon Polarity tester in it.
And when the Solenoid is activated by the black button, it draws 240mA, to discount Ghost Voltages.
I use one of these and it has never failed me yet, even up to 750VDC.
