| br>I bought one those 1/8” jacks with LED as an add on with another purchase. Later I thought why’d I spend dollars on that thing it’s probably just a resistor and a bicolor LED!
Make your own from three parts. I had a few 1/8” jacks spare. I used a two legged bicolor LED and a 470r resistor.
Just connect each leg to one lead on the Jack with the resistor in series with one of those legs.
