How to Install a Motion-Activated Security Light

In this video, Ask This Old House Master Electrician Scott Caron installs a light above a garage to illuminate a dark driveway.

Steps:
1. Find an existing source of power near the location of the security lighting and shut off the power to that source.
2. Cut existing wire connections using the wire cutter.
3. Drill an outlet hole through to the exterior siding using a power drill with 1⅜-inch spade bit. Run 14-gauge wire from the inside location to the outdoor location.
4. Assemble the security light fixture.
5. Attach power wires to the light fixture wires and cover with wire connector nuts.
6. Roll out flexible putty and attach around the hole on the exterior of the house. This will serve as a barrier to make it weather-tight.
7. Attach the light fixture and electrical box to the outside siding using a power drill and screws.
8. Replace existing outlet with a switch-over-outlet device that can serve as an override.
