Christmas Light Tester

[StewieGriffin]

I saw an interesting item, an expensive christmas light string tester.
Apparently, you plug the light string into it, press a button, and the bad
bulb or socket buzzes. You can see it at

Any idea how this works (and why it's worth $200)?

Something that generates a large enough voltage spike to jump across the
broken element, but low enough amperage not to damage the good elements?

Just a guess.

I have a vision of the unwary homeowner on his extension ladder under the
2nd story eave reaching for that buzzing bulb and as the glass seperates
from the base he finds himself with the 60hz equivelant of an automotive
ignition coil in his hand.
Sounds dangerous.
