    3-way switch wiring
    I am having trouble wiring a 3way light system. I am looking to run two lights from both ends of the switches. My explanation is I had a single light & switch at the top of stairs and a single light & switch at the bottom of stairs. I have ran 12-3 wires between switchs but not sure how to wire in to 3way switchs to supply both lights from both ends.

    Power to switch to light to switch to light.
    Light in middle of run and end of run, or beginning of run and end of run

    :( If any one can help. Or is it possible?

    Here is a diagram of a 3 way- 4 way switch. Just imagine the 4 way is not in the circuit. You will be unable to switch two lights ,one from each end of the circuit.

    You could have ran a 4 wire plus ground cable to carry the switched leg to the other end of the circuit to feed the other light, but unfortunately, not with 3 wire between the two switches.
