Installing a Motion Sensor Light Motion sensor lights are perfect to light the way when you return home late at night or to discourage potential intruders. If you have an existing floodlight, they are especially easy to install.

Before you begin:
Choose a fixture that will let you control the time and the sensitivity to motion. It’s even better if it’s connected to a switch in the house, that way you can override the motion sensor to keep the light on or off.

Follow These Steps

Steps 1 - 3 of 3Print Project SheetEmail a Friend

  • Step One

    Shut off the power at the service panel and remove the existing floodlight. Run the wires through the rubber gasket and splice them with wire nuts. While mounting the light to the box, position the gasket so it will keep the box dry.

  • Step Two

    Restore power and then loosen the locknuts and twist the light until it is directed where you want it. Tighten the locknuts. At night, turn the light on permanently by flipping the wall switch off and on again. Aim the lights and tighten the nuts to hold them in place.

  • Step Three

    Activate the motion sensor using the manufacturer’s instructions and choose how long you want the light to stay on. Test the sensitivity of the sensor by walking around it. Adjust if necessary.
