Hello, I hope everyone is well.
I am drawing a blank on a simple circuit I am putting in a power supply. All I want it to have an LED turn on when power is applied, and when power is cut off . I would like another LED to turn on with the previous one turning off. I know I can do it with a relay, but also remember a simple circuit I've seen in the past that does it with a transistor, and I believe a diode or 2. Thanks for the help..
