Energy-saving features, customizable colors, intense illumination—these are the things that car lighting enthusiasts love about LED light bars. These light bars allow for better road visibility when going off-road and are very reliable during inclement weather conditions.
So where do you find a light bar installation shop near you? The answer: your garage. Simply follow these five easy steps on how to install LED light bar and you won’t have to pay a single cent to a mechanic!
Step 1: Prepare the vehicle
First, disconnect your car battery. To avoid shorting it, remove the wire of the ground terminal first, followed by the positive terminal.
Step 2: Set up the LED light bar
After prepping, mount your light bar. It is important to consider sturdiness when choosing a mounting location. It should be steady enough to hold your light bar in place whenever you go off-roading. In addition, the area should be safe for drilling, meaning, no other automotive parts should be compromised during installation.
That said, a safe drilling procedure is a must. Mark your holes using a marker pen first before puncturing anything. Attach the bolts but remember to screw them loosely because they will be adjusted multiple times later on.
The usual LED light bar kit comes with mounting brackets, wires, nuts and bolts. In most cases, a wiring harness is also included. If not, then you can always purchase it separately. Always consider the LED light bar type and your vehicle’s wiring system when buying a wiring harness. Wiring can sometimes be tricky, so to steer clear of possible short circuits, always refer to your light bar wiring diagram.
Make sure that your wiring harness is untangled to properly identify your wires. The harness consists of a switch, a red power cable and a black ground cable (comes with ring terminals), a relay, and a pair of connector wires (negative and positive) for the light bar.
Step 3: Set the switch in place
Start by detaching the switch wire segment from the main harness, then route and find your way through your firewall to reach the dashboard. After finding the desired location, use an adhesive type to put the switch in place. Reconnect the other end wiring line of the switch back to the wiring harness.
Step 4: Position the relay and the cables
You can bolt the relay anywhere on your firewall as long as its location is near the battery. Afterwards, take the red positive cable and mount it directly to the red terminal of the battery. Conversely, ground the black negative cable by attaching it to the chassis. Make it a point to cleanly tuck the excess wires and cables in the engine bay and avoid putting the wires close to high-heat zones.
Step 5: Wire harness to the light bar
Now work on the remaining set of wires on your harness. They are the connectors to your LED light bar. Run them to where your light bar is. Hook up the connector wires to your light bar (red to red and black to black). When everything is in place, go back to your light bar brackets and adjust the light bar’s angle. Secure by tightening the bolts once you’re satisfied with the position. That’s it! You can now turn on the light and enjoy your upgraded lighting system.
Things to Keep in Mind
LED light bars are off-road lights. In most states, they are not legal to use on streets and highways. As such, it’s imperative to check your local road laws first before mounting one on your car.
