How to Install an Exterior Light Fixture

1. Tools and Materials Needed

• Tools:

  • Screwdriver

  • Drill and drill bits

  • Voltage tester

  • Wire strippers

  • Caulk gun

  • Utility knife

• Materials:

  • Exterior-rated light fixture (sconce, lantern, etc.)

  • Weatherproof mounting block

  • Electrical box (if one isn’t already installed)

  • Outdoor-rated caulk

  • Builder’s felt (for waterproofing)

  • Drip edge (optional, for extra protection)

2. Turn Off the Power

• Locate the Circuit Breaker: Switch off the power to the existing outdoor light fixture at the circuit breaker.

• Use a Voltage Tester: Double-check that no power is flowing to the wires before proceeding.

3. Prepare the Mounting Area

• Remove the Old Fixture (if applicable): Unscrew the existing light fixture and disconnect the wiring.

• Install a Weatherproof Outlet Box: If there’s no existing electrical box, install an outdoor-rated junction box.

• Apply Builder’s Felt: Staple builder’s felt around the electrical box to create a moisture barrier.

• Attach a Drip Edge: Install a drip edge above the fixture location to divert water away from the fixture.

4. Install the Mounting Block

• Cut a Notch for Siding: If your home has siding, cut a notch in the mounting block to fit securely over the siding.

• Secure the Mounting Block: Attach the mounting block over the outlet box using screws.

• Apply Caulk: Seal around the edges of the mounting block with weatherproof caulk to prevent water intrusion.

5. Wiring the Light Fixture

• Connect the Wires:

  • Black Wire (Hot) to Black Wire from the fixture.

  • White Wire (Neutral) to White Wire.

  • Green or Bare Copper Wire (Ground) to the Ground Wire or Electrical Box.

• Secure with Wire Nuts: Twist the wires together and secure them with wire nuts, ensuring a tight connection.

• Tuck Wires Inside the Box: Carefully push the wires into the electrical box to avoid pinching.

6. Attach the Light Fixture

• Align the Fixture: Position the light fixture over the mounting block and secure it with screws.

• Seal Around the Fixture: Apply a bead of outdoor-rated caulk around the fixture base to keep out moisture.

• Install the Light Bulb and Cover: Screw in an outdoor-rated bulb and attach any glass covers or decorative elements.

7. Restore Power and Test

• Turn On the Breaker: Restore power at the circuit breaker.

• Test the Light: Flip the switch to ensure the fixture works properly.

• Adjust as Needed: If the light flickers or doesn’t turn on, double-check wiring connections and secure fittings.
