daft question on LED indicators and high VDC

[Binary]

no, not a metal can version a basic 5mm LED .....my thoughts the LED stays on, capacitance on one of the LED pins is the switch so just touch the resin or get close and the switch action operates the led to turn off or any output can be turned off

You won't get enough pick up from the LED lead to give you a reliable operation, if you ramp up the sensitivity you will get switching from any electrical noise, so again it won't be reliable.

I don't want to mislead you this has been done, how its been done and what with I'm not sure
I was going to use an Arduino which will easily give a output for a LED it can also be used as a sensor
the method in combining both switch with LED would make or break it.
this is for only a prototype, then code for 8052
