Hennepin, IL | Something that would light up when the circuit at the other end of the cord is closed and go out if its open. Or vice versa for that matter. Got heat lamps in a couple drinkers and having something simple like that would save a lot of time checking drinkers for burnt bulbs, etc. Only have drop cords running to them at the moment so it would be pretty easy. I know how I could make one in theory, just didnt know if the was such a thing I could just order. Not even sure what to google search. | |
