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)? T #### The Al Bundy Jan 1, 1970 0 StewieGriffin said: I saw an interesting item, an expensive christmas light string tester.

Maybe another idea, generate some HV and see which bulb shows some blue
light

I suppose you could save a few dollars every year with this and eventually they
add up to the \$200 ...
