Cnnected from L to E a neon on a 220k resistor will add in the region
of 0.7mA. An ultrabright LED can be run off much less than 1mA with
decent light output. And if you run it from a CR dropper the power
diss would be even tinier. The LED would need a rectifier of course.
NT
Wouldnt this add to RCD trip current?
Why not wire it between L and N?
And how does the switchlite work?

it glows when not switched on,
but has no Neutral or Earth connection,
is it like my neon mains testing screwdriver?
