How to Wire LED Offroad Lights

How to Wire LED Offroad Lights

Camping and offroad travel are fun to do. You can have it with your family or friends and enjoy mother nature. It is more fun if you are going to stay out for several days or might even take weeks. Everything is all prepped up and set, and you are good to go. One of the things that you prepped aside from your food is your car – your offroad vehicle. Thinking that you will take days up to weeks away from home, you need as well precautionary measures. In case of an emergency, you are prepared, and this is where your offroad lights come into place. Your offroad LED lights will serve as your guide and light even at the darkest of the night. Since your travel is near, your time may be short if you will have your car brought to a shop.

Worry not, some ways could help you in wiring your LED offroad lights at the comfort of your garage. There are things and supplies you will need to have first before proceeding to your project.

What You Need to Do

Here are the things that you will be going to need:

  • LED Offroad lights
  • Power supply (you can have a 9-volt battery for testing)
  • 30 amp fuse blade and fuse holder
  • Relay and relay holder
  • Switch
  • 14 or 16 gauge positive and negative wires
  • Tube connectors and crimping tools

Step 1

Check your LED light first if it is working, with help from your 9v battery. As you can see, the light has two wires, the positive (red) and the negative (black), and see if it passed your light test. 

Step 2

Next is your relay; this is the controller of the current from the power source and to the LED light. The good thing about the relays is that they come with a wiring diagram. It shows which wire should go to which part it will get wired. Mount the relay and the relay holder, then, extend your wires using tube connectors, 14 or 16 gauge wirings, and crimp tools. Take note, prepare your wires first, and don’t attach them yet to your power source. 

Relay diagram codes:

30 – connects to the power source (positive side of the battery)

85 – connects to the ground (either the bolt of the card or the negative side of the battery)

87 – connects to the accessory (LED light)

86 – connects to the switch

Step 3

Next is to extend the wiring of your LED lights as well using tube connectors and your 14 or 16 gauge wires and crimping them. If your switch has three chromes in it. The middle chrome will be the one to be connected with the wire from the relay that connects to the switch. The remaining two chromes will be connected with a separate ground and separate constant power to power the switch.

Step 4

The next thing you will going to do is to extend the negative wire of the LED light as well, and this will serve as the ground later on. There, your wire connections are made, and it is ready to be mounted in your car.

These steps will help you in wiring an offroad LED lights using a relay. Remember that you should always have the relay so that you could avoid possible problems with your light.
