You need to invest in a tester. Not a tester that works of inductance
like the pen testers. Even the neon testers are not reliable. We will
not let out employees use them as they are fallible.
Buy a wiggy

Or some sort of voltage tester that tests ac and dc. Some are fairly
inexpensive.
You are checking LIGHTS on testers and you need to be checking voltage
If you are using a neon tester and you go between the wires when the
switch is off and you get a small glow that could be a small amount of
voltage on it from inductance or a loaded neutral down the line and
your neon tester is seeing it.
If you get your voltmeter I would expect you may have a couple volts
between ground and neutral at the point you tested and got a small
glow.
A wiggy has coil in it it will click to the volatage applied to it.
Voltmeter is better but you need to read the manual to learn all the
settings
