Wanted Need Help Please

[frank]

Does anyone remember seeing a 1/4 inch headphone jack with a light incorporated into the top of the jack and when a signal from the detector is transmitted to the jack the light lights up ?
This is for a hearing impaired person I am trying to help out.
I have seen these advertised for sale in the past and can't remember where to get one for him so he can use a detector.
Any help here much appreciated thanks Frank C.

I have built similar devices in the past. I have installed a bright blue LED on my harbor freight pinpointer that lights when target is detected. It is easy. merely wire the led to the speaker. On my 2 Box detector I wired a LED to the speaker. The problem with the jack is that it is usually facing in the wrong direction. Just measure the voltage present on the speaker when it is signaling, then get a LED with a matching voltage. Leds are usually 1.5v or 5v with a fer odd balls out there. Hope this helps, Frank
