How to Install Outside Coach Lights

Install a fixture box at the desired location for the coach light. In new construction, the fixture boxes are nailed to the studs before the exterior wall sheeting and siding is installed. Cut a hole in the siding, from the exterior, for remodel projects. Install special fixture boxes that clip into place.

String a wire to fixture box. In new construction, the wires are strung when the walls are unfinished on the inside. The wire will attach to the electric source of an outlet, other light fixture or the house’s breaker box. In remodeling projects, the wires are pulled through the wall using fish tape. Fish tape, a semi-rigid metal strip, is pushed into the wall opening toward another outlet or light fixture. Once the other fixture is reached, the wire is attached to the fish tape and pulled back to the new coach light fixture.

Cut the wires to a length, leaving about 4 inches in the fixture box. Attach the wires of the coach light to the same colored wires of the house wire, using wire nuts. Wire nuts are plastic and copper connectors that hold wires together. First twist the wires together and then screw the wire nuts on the wires.

Fasten the coach light fixture to the fixture box. Most fixtures utilize two screws through the fixture into the threaded holes in the box. Tighten the screws into place. Apply caulking around the light fixture to prevent water from entering the fixture box.
