    Good try, but what happens if two switches open?

    Will 2 diodes and two resistors all in series sink enough curent to switch the Bob?

    How about three?

    Edit: I'm not explaining that very well am I? You aren't actually breaking the circuit, you are still requiring current to flow and light the LED's.
