Stop walking across a dark room to turn on the light. Install a 3-way switch and control lights from two locations.

Here's how to swap outdated three-way light switches for something much better.

To make the wiring work flawlessly, so your husband becomes a lover of these switches, you install the same special three-wire cable between all the three- and four-way switches in the circuit.

In the diagram on the link they are using a three conductor cable after the first three way switch. Black, Red, and White with a separate ground.
