Mount the Halogen Off-Road Lights
First step your halogen off-road brilliance installation development by securely mounting the lights to the away of your vehicle. Depending on your needs, paragon locations might encompass the front bumper or brush guard (where installation Testament be simplified by the proximity to the engine bay) or on an overhead roll bar. The lights Testament doable come with installation and mounting hardware. For this reason, it's important to always turn off the lights when not in use. If left on, they may drain the battery to a point at which it is unable to start the car.
Depending on how many lights you are installing and their wiring configuration, it may be cardinal to associate a wire to Everyone luminous and splice the group of wires into a unmarried front rank for wiring purposes.
Run the Single Wire Into the Cabin
With a unmarried certain wire connected to the halogen glassy(s), lope the wire into the inside of the passenger cabin. If your lights are mounted to the front bumper or brush guard, you may be able to run the wire through the engine bay, passing it through the firewall into the interior cabin space. If the lights are mounted overhead, you may need to run the wire inside or around the upper roll bar, bringing it into the cabin area by either drilling a hole or running the wire through a door jamb. Depending on your specific vehicle model, wiring conduits may already be in place to ease this process.
Connect the Positive Wire to a Toggle Switch
Inside the passenger cabin, mount a two-way toggle switch (readily available at electronics supply stores) in a convenient and easy-to-reach location. Run the wire from the lights to one terminal of the switch, taking care to hide the wire under upholstery, carpeting or along the underside of the dash as necessary. At the switch, connect the wire to one terminal using electrical tape. For more permanent and secure installation, solder.
Run a Wire From the Switch to the Battery
Run another wire from the switch location to the vehicle's battery terminal by passing the wire through the vehicle's firewall and running the wire along the engine bay, taking care to secure the wire so it is not damaged by a closed hood. Depending on your specific vehicle's configuration, at least one conduit between the passenger cabin and the engine bay may already be in place. At the battery terminal, secure the end of the wire to the battery cable by stripping the insulation from the end of the wire and attaching it to the cable terminal. Use either electrical tape or solder (soldering is highly recommended due to the environmental nature of the engine bay). Attach the end of the wire still inside the passenger cabin to the other terminal of the switch, using the methods described in Section 4.
Connect the Ground Lead
Back at the halogen lights, one additional wire lead should still be unused. This lead, probably color-coded black, is the negative lead and should be connected to a grounding point somewhere on the vehicle's chassis. This connection can be accomplished by securing the loose end of the wire to a metal surface under a screw (so that the wire is tightly held against the metal by the screw) or by running the wire along the same path created in Sections 3 and 5 to connect it to the negative (black) battery terminal.
Clean and Test the Halogen Lights
With all wires run and secured in place, replace any body panels or carpeting removed while running wire. Securely plug any holes created and vacuum debris left from the installation process. Because the lights are wired directly to the battery, they will work regardless of whether the car is running. To activate the lights, flip the toggle switch to the "On" position (if so labeled) and inspect the lights. If they are dim or fail to illuminate altogether, check all wiring connections to verify that no wires have come loose.
Remember to Turn Off Your Lights
As stated above, the direct wiring of the halogen lights means they will stay on whether the vehicle is running or parked. But, confident brands of lights and definite installation locations may wish specialized mounting procedures up to and including welding the lights in distance.
