How to Wire Two Outside Motion Security Light Fixtures: The Most Common Wiring Connections for Two Outdoor Light Fixture.
Wiring a Switch for Two Outside Motion Lights
Electrical Question: What is the correct wiring when adding a second outside motion light to an existing switch?
- It is not feasible to wire from the existing light so, the wiring would have to be from the switch.
- I know all the white wires have to be put together along with the grounds.
- Do both black feeds to the lights go on the terminal together ?
This electrical question came from: Ron, a Homeowner from Allentown, Pennsylvania.
Thanks for your electrical wiring question Ron.
How to Wire Outside Motion Security Light Fixtures
Application: Security Light Fixture Wiring.
Skill Level: Beginner to Intermediate. This electrical wiring project is best performed by a Licensed Electrical Contractor or Certified Electrician.
Tools Required: Basic Hand Tools and Safe Ladder.
Estimated Time: Depends on personal experience, the light fixture and access to the light fixture.
Precaution: Identify the light fixture circuit, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Replacement parts for the light fixture should be compatible with the type of lamps that have been installed.
- The Most Common Wiring Connections for Two Outdoor Light Fixture
- The black wires going to the motion light fixtures need to join together, but not on the switch, instead splice the two wires after the switch.
- With this wiring configuration you would end up with 3 black wires:
- One black wire for the switch as the power source.
- One black wire for light #1.
- Another black wire for light #2.
