Is it possible to power an LED from a light switch (live only
connections,
and possible earth) so an illuminated LED can indicate if the light is
on
or
off?



Why not use a neon lamp like the ones used in cooker units ? These don't
have to be wired to anything fancy like diodes or heavy resistors. They
are
easily obtained and very cheap, and can be wired to live and earth if your
not using an RCD breaker. It can be done remotely from one room to
another,
which I do quite regularly to indicate when water heater thermostats are
switching on and off.

Like these ones:

Just thinking out loud here, but wouldn't the big GLS lamp in the middle of
the ceiling, yes, the thing inside that light shade, tell you if the switch
is on or off ?
