What are the "touch light" indicators?
Is that the one that's a little neon bulb in a screwdriver handle where you touch the copper "cap" at the end and stick the other end into the socket holes?
If that's the one, I have one....makes a good mini screwdriver...but I'm too chicken to stick that into a wall socket.
I use a little gadget that consists of a series of neon bulbs and two wire probes.
Each bulb is marked with a voltage (110, 220, etc.) so depending on which one lights up, that's what the voltage is across the circuit. Then of course there's my multimeter...
