Well, if the neon was used as an indicator on a 240V supply then it
would be fine. The general theory behind using it as a test instrument
is the flaw with the neon screwdriver.

Neon lights seem to die after a few decades, which is annoying.

Possibly, but I'd hardly call that unreliable in light emitting device
terms. ;-)

On reflection, this may not be that much of a problem on a screwdriver.

Dunno if they are susceptible to dropping? Don't trust neon screwdrivers
anyway - never have.
