I'd like to use a bicolor LED powered from a single power supply (either 0-5V or 0-12V). I have two applications. One driven by a comparator (LM393 most likely) and the other driven by a simple transistor with both emitter and collector available. But for some reason the solution elludes me and I can't figure out how on paper to make it work. Specifically, I'm looking at All Electronics Parts LED-6 (2 pin, reverse polarity to change color), and LED-141 (3 pin).
