How to add LED or Neon indicator to existing 240v wall light switch?
I want the led to lite when the switch is at OFF position and led to turn off when light switch is at ON position.
I have already installed those led indicator switches from Amazon but I would like to know to make one.
Will appreciate schematic of the circuit.
Thanks!

Put the led/neon across the light switch terminals, so that when the switch is On, the neon is shorted out Off, and will be On when the switch is turned Off.

LED to line without isolation is a prohibited topic.
Maybe - maybe not. the only practical way is prohibited, but may be OK if not accessible. Code compliance is a whole nother can of worms.

Pretty sure there's off the shelf switch plates with indicator lights.
