[aprssig] Electric Field Sensor (XMAS lights)?

If the string worked last year and has a flasher bulb, give the flasher a thump with your finger. They are notorious for sticking open. This only applies to the older incandesces type of  Christmas lights.

Sorry for the off topic.

Will one of these cigar sized (yellow) electric field sensors be any use in  finding the bad bulb in a series XMAS light string?

It beeps in the presence of an electric field and detects AC about 6 inches away.th this?

I can find no difference all along the string.  But then this is a 3 wire string with a receptacle on the end so there is AC end to end, even though there is a series bulb out.

Maybe this technique will work on a 2 wire loop string and not a 3 wire?

I'm happy to cut off the end plug and pull out the 3rd wire if someone claims it will work on a 2 wire string.

Sorry for the off topic post, but I'm probably not the first one with this dumb question at this time of year.
