How to Build the Motion-Activated Light

Installing this DIY motion-activated garage light is a very straightforward process. Follow these steps:

Step 1: Turn Off Power

Before doing any work, locate your garage circuit breaker box and switch off the circuit that powers the garage. This ensures you can work safely without risk of electric shock.

Step 2: Mount the Fixture

Decide where you want the light mounted. Most motion sensor lights are designed to mount directly to the ceiling or wall. Use double-sided mounting tape or screws to firmly attach the fixture.

Step 3: Connect the Wires

The motion sensor light will have three wires - line (black), neutral (white), and ground (green or bare copper). Connect these wires to the matching wires in the electrical box using wire nuts. Line to line, neutral to neutral, ground to ground.

Step 4: Secure the Wires

Neatly tuck all the connected wires into the electrical box and secure the motion sensor light fixture in place.

Step 5: Turn Power Back On

Head back to the breaker box and switch the circuit breaker back on. The light is now ready for motion-activated operation.

Step 6: Test and Adjust

Turn on the light manually using the built-in switch. Walk in front of the sensor and make sure the light turns on like it should. Refer to the manufacturer's instructions to adjust the sensitivity and timer settings if needed.
