Exterior Garage Light Install: Quick Sheet

Replace exterior garage light fixtures, including how to verify the power is off, clean out old buildup, dry-fit the mounting plate, correct mounting-screw length, connect the wiring, install the rubber washers, seal against uneven siding, and test the dusk-to-dawn sensor before finishing.

Important: Turn off power at the breaker and verify the circuit is de-energized with a multimeter before touching any wiring. Follow the fixture manufacturer’s instructions, and hire a licensed electrician whenever the wiring, junction box, grounding, or exterior installation conditions are unclear.
