4.1 Tools Required
- Wire strippers/crimpers
- Electrical tape or heat shrink tubing
- Appropriate grommet (not included)
- Drill with hole saw (if creating a new mounting hole)
4.2 Installation Steps
- Prepare Mounting Location: Identify a suitable flat surface for mounting. Ensure there is enough space behind the mounting surface for the light's depth and wiring. If a new hole is required, use a hole saw to create a circular opening appropriate for a 4-inch round light and its grommet.
- Install Grommet: Insert the appropriate rubber grommet (not supplied) into the prepared mounting hole. Ensure it is seated securely.
- Wire Connection: The light comes with a hard-wired 3-way molded plug. Identify the positive, negative, and ground wires from your vehicle's electrical system. Connect the light's wires to the corresponding vehicle wires. Typically, the white wire is ground, and the black or red wire is positive. Refer to your vehicle's wiring diagram for specific color codes. Ensure all connections are secure and insulated using electrical tape or heat shrink tubing.
- Mount the Light: Carefully push the LED utility light into the grommet until it is fully seated and flush with the mounting surface. The grommet should hold the light firmly in place.
- Test Functionality: Once installed, reconnect the power source and test the light to ensure it functions correctly.
