I used one of the BG light switches and a 12W LED bulkhead from toolstation. The switch has an indicator:
You can wire it in a so-called 'locator' mode. Where the indicator goes on when the light's off.
It achieves this with neon wired across the connection, and it conducts just enough with the switch in the 'off' position to energise the light fitting:
And you guessed, it gives enough light to see the goddam switch in the first place, thus making the indicator redundant. Out of idle curiosity I measured the current, will cost me about 20p/year...
