You have a filament bulb.
Its like a coil.
However small a current or voltage you apply to it, being you
have almost dead batteries, when you turn it OFF you collapse
the ether field which WILL cause a spark at the switch point
meaning a large voltage was generated and illuminated the
bulb. I am thinking now the bulb illuminated and not the filament.
If you got filament light momentarily when you turned the flashlight
ON, then I don't know how that happened.
When Tesla turned on Edison power there was sparking.
A telegraph line effect might at work in that case which is
a series of inductors and capacitors.
