One of the simplest, most effective ways to enhance the safety and security of your home is to add a motion-sensor floodlight to the garage. The dual-lamp model installed here comes on automatically if something—or someone—crosses its field of vision.
If you’re hesitant about working with electricity, don’t worry. We’ve greatly simplified the process by safely tapping into an existing garage circuit and by running the wires through surface-mounted metal tubing, called conduit. This technique speeds the installation by eliminating the need to blindly pull wires through walls and ceilings.
All of the supplies required for this project are sold at hardware stores and home centers, including the thin-wall metal conduit, which is referred to as EMT for electrical metallic tubing.
