How about a light switch with a motion sensor? They make ones that are occupancy detectors (detecting motion and then turning on), and vacancy sensors (detecting absence of motion and then turning off). They'll also have a button which can manually toggle the light on or off, and you can set the sensitivity and how long an absence is required before the ...

Old 3-way switches should have 3 wires running between them - two messengers and the return. While this isn't always possible depending on where power was fed to the circuit, my preferred way is to re-task them to be always-hot, switched-hot, and neutral. I put "smart switches" at each location, which provide the auto-off feature you require. There are a ...
