How do you wire a 3 way switch with power feeding switch then two lights then switch?

To wire a 3-way switch with power feeding the first switch, connect the incoming power's hot wire to the common terminal of the first switch. Then, use two traveler wires to connect the two traveler terminals of the first switch to the corresponding traveler terminals of the second switch. From the common terminal of the second switch, run a wire to the first light, and then connect the second light in series from the first light. Finally, connect the neutral wires from the power source to both lights and ensure all grounds are properly connected.
