How to install LED Light Bar
Aftermarket driving lights like spot lights and LED light barsled slim light bar, led light bar for suv) offer the ultimate driving light solution for every vehicle. From trucks and four wheel drives right through to sports cars and family sedans.
It is the responsibility of the vehicles owner to abide by the relevant state and territory rules and regulations. Driving light bars are recommended for off road use only.
Wiring them up doesn’t have to be hard, if you have the right tools. We recommend using a driving light harness which use a simple plug-n-play design meaning all the hard work is already done and you don’t need to spend hours wiring. The kit works by tapping into your cars headlight circuit and feeds the power from your high beam, right to your driving light. You will also have the option to turn the light off completely using the master included switch.
Here’s how to do it. (best quality led light bar, best affordable led light bar

What you'll need:
  • 1, SCA Driving Light Harness
  • 2, LED light bar
  • 3, Drill, bits, and self-tapping screws
  • 4, Socket set
Step 1 - Mounting the light bar
Start by mounting your light bar or spot lights your vehicles bullbar, driving light mount, roof cage/roof rack or other suitable sturdy location, keeping in mind local laws surrounding driving light placement.

Step 2 - Disconnect "Negative" terminal
Disconnect the negative terminal from your vehicles battery before commencing any further work.

Step 3 - Mounting the relay & fuse
Find a suitable location to mount the relay and fuse, preferably on the inner guard using an existing bolt, or a self tapping screw.
Ensure that the wire for the fuse will easily reach the battery, and connect the ring terminal to the positive terminal.

Step 4 - Finding your vehicle's headlamp wiring
The light bar needs to be triggered by activation of your high beam.
Locate the back of your high beam headlight globe on the side closest to the relay, and remove the plug from the back.

Step 5 - Attaching the headlamp adaptor
Choose the headlamp adaptor supplied in the kit which suits your plug, and connect this to the factory plug. Another end connects to your headlight globe, and the third end plugs into your new harness.  These plugs will only fit one way.

Step 6 - Mounting the switch
Now mount the switch in the cab locating it convenient to the driver.

Step 7 - Running the wires through the firewall
Run the plug through an accessible grommet in the firewall through to the engine bay – by either making an incision in the grommet or poking through with a sharp object.
Taping the plug to a long piece of fencing wire will help it through any tight places.

Step 8 - Connecting the two harnesses
Connect this plug to the one which comes off your relay.

Step 9 - Connecting the light bar/driving lights
The final piece in the installation is the plugs for your light bar.
The single plug must be connected to the relay, and the ring terminal on this end needs to be connected to an earth. Either directly to the negative terminal of the battery, or to a bolt with bare metal contact to the body.

Step 10 - Taping additional wiring away
Now with the plugs that connect to the lights, if you are using a light bar, only one of the plugs needs to be connected.
The second plug can be taped up out of the way, or you could use this wire for an additional light bar. If you are wiring up spot lights, connect a plug to each light.

Step 11 - Reconnecting the negative terminal
Now you’re on to your last step, reconnect the negative terminal to your battery and you should be good to go!
Put the switch for your new lights in the “on” position and turn on your headlights.

Step 12 - Testing
The light bar should not illuminate until you flick on the high beam.
With the high beam and the light bar on, put the switch in the “off” position.

Step 13 - Finished!
If your light bar switches off and your high beams remain on, you have successfully wired in your own LED light bar.
