Roger, I am not sure what you are looking for.  One thing that I have is a 
commercially available  DC audible test light.  It has a pointed probe and no 
additional wires.  The round case that the probe sticks out of is metal and 
inside there are two batteries, a buzzer and a light on top.  When the probe is 
touched to a DC source and your body is touching a good ground the light turns 
on and the buzzer sounds.  Yes the tool works through the human body.  This is 
great for one handed testing for DC power.  The batteries are for sounding the 
buzzer and lighting the light.  I think the range is something like 0.5 or 1 
volt to 25 volts.
I think the price is around $19.00, it is quite a while ago that I got mine.
