Don’t worry; it’s a fairly easy process that only requires a few simple tools.

How to Wire Headlights Directly to Battery

In this blog post, we’ll walk you through the steps on how to wire headlights directly to battery. So, if you’re ever in a situation where your headlights aren’t working properly, don’t hesitate to give this tutorial a try!

Why Should You Wire Headlights Directly to Battery?

There are several reasons why you might want to wire your headlights directly to your battery. One reason is that it can give you a brighter light. This is because the battery can provide more power than the headlight switch, which means more current will flow to the headlights. This will make them brighter and more visible.

Another reason is that it can help prolong your headlights’ life. When you wire them directly to the battery, they won’t be turned on and off as often, which lasts longer.

Finally, wiring your headlights directly to the battery can give you more control when they’re turned on and off. The headlight switch will no longer be involved to turn it on and off.

Things You’ll Need

  • Wire
  • Electrical tape
  • scissors
  • Utility knife
  • Phillips head screwdriver

How to Wire Headlights Directly to Battery Step by Step Guide

Step 1: Disconnect the Battery

You will need to disconnect the battery before you start wiring the headlights. This ensures that there is no power running through the system while you are working.

Step 2: Remove the Headlight Assembly

To access the back of the headlight assembly, you will need to remove it from the vehicle. This is typically done by removing a few bolts that hold it in place. Consult your car’s owner manual for specific instructions on doing this. Once the headlight assembly is removed, disconnect the wires that connect it to the car’s electrical system.

Step 3: Cut the Wiring Harness

Using a wire cutter, cut the wiring harness to the point where it meets the battery. This will give you two pieces of wire to work with, one that leads to the headlights and one that leads back to the car’s electrical system.

Step 4: Splice the Wires Together

Use a wire splicer to connect the two pieces of wire. Ensure that the wires are securely connected not to come apart while working.

Step 5: Connect the Negative Wire

Connect the negative wire to the negative terminal on the battery. If you are using a relay, connect the negative wire to the terminal on the relay that is labeled “86.” This will complete the circuit and allow current to flow to the headlights. Use electrical tape or connectors to secure the wire to the battery terminal.

Step 6: Connect the Positive Wire

Once you have your negative wire securely in place, it’s time to work on the positive side. To do this, take your red wire and strip about 1/2 inch of insulation off the end. Then, take your eyelet connector and crimp it onto the end of the wire. After that, connect the other end of the eyelet connector to the positive terminal on the battery. Again, use electrical tape or connectors to secure the wire in place.

Step 7: Test Your Work

Now that both wires are connected, it’s time to test your work. First, turn on the headlights and see if they are working properly. If they are, then congratulations! You have successfully wired your headlights directly to the battery. If not, you may need to check your connections and ensure they are secure.

There you have it! Now you know how to wire headlights directly to battery. This is a great way to ensure that your headlights always have power, even if your car’s electrical system fails. Follow the steps carefully and always test your work before driving your car.
