Years ago I had a prick pen, now, now that's enough lads, allow me to continue.
It was like a ballpoint pen with a very sharp short needle at one end and a small bulb at the other end, half way along its length it had a flying lead about 2 foot long with a small crocodile clip.
Now somehow the needle and the centre contact on the bulb must of been connected and the flying lead to the mount or negative side of the bulb.
It was brilliant for finding out if cables had power and you could work your way along the length of a cable or wire and find the exact point the the break was. The needle made such a fine hole in the insulation just rubbing that sport hard with a thumb nail and it seemed to disappear.
I,m going to make one, it's not rocket science. Sewing machine needle, six inch length plastic tube, small bulb (12 volt) and bulb holder, wire a crock clip and builder bucket full of aradite. Jobs-a-Goodun
Update:
thinking about it you could do exactly the same thing using a multi meter with a very sharp positive probe
