The Best Way to Add a Motion Detector to an Old Light

A motion detector functions by tripping a circuit when its sensor detects a movement. The best way to add a motion detector to an old light that uses an incandescent bulb is to avoid any wiring and use a self-contained unit that can screw into the light socket. This makes for a simple procedure that does not require any tools or electrical skills. The self-contained motion detector can be purchased at hardware stores or hobby shops, and will work for indoor and outdoors fixtures.

Instructions

1. • 1

     Unscrew the incandescent light (light bulb, floodlight, etc.) from the bulb socket. Place the incandescent light aside for now.

   • 2

     Screw the base of the self-contained motion detector into the old light's bulb socket. Stop screwing the base into the socket when resistance is felt.

   • 3

     Screw the incandescent bulb into the motion detector's bulb socket. Stop screwing the bulb into the socket when resistance is felt. The motion detector can now be configured for use by adjusting its controls.
