As cars become more and more advanced, it’s important to know how to wire led light bar without relay. While this may seem like a daunting task, it’s not that difficult – as long as you have the right tools and instructions. In this blog post, we’ll walk you through everything you need to know about wiring led light bars, so you can get back to driving in style.
Summary: If you’re looking to install a LED light bar without using a relay, there are a few different ways to go about it. One way is to use a switch to control the light bar’s power. Another way is to install a series resistor and use an electronic circuit to control the light bar’s power.
Why Wire Led Light Bar Without Relay
There are a few reasons you might want to wire your led light bar without a relay. First, it can be a more affordable option – relays can be expensive, and they’re not always necessary. Additionally, wiring your light bar without a relay can be a good way to protect your car’s electrical system. Relays can sometimes create a lot of heat, and if they fail, they can potentially damage your car’s wiring.
Is Relay Important for A Light Bar
That depends on how you’re wiring your light bar. If you’re using a relay, then yes, relays are important. However, if you’re wiring your light bar without a relay, you don’t need to worry about it. In either case, it’s important to use the right tools and instructions to wire your light bar correctly.
Required Materials
- A drill
- A drill bit
- A wire stripper
- Wire (we recommend 14-gauge)
- Electrical tape
- A friend (optional, but helpful)
How to Wire Led Light Bar Without Relay Step by Step Guide
Step 1: Select the LED
You need to purchase quality LED lights. There are many different LEDs available on the market, so it is important to select one that will be appropriate for your needs. The most important factor to consider when selecting an LED is the power output. Make sure to select an LED with a power output appropriate for your application.
Step 2: Select an Appropriate Power Supply
The next step is to select an appropriate power supply. To wire a LED light bar without a relay, you will need a power supply that can handle the amperage required by the light bar. Most LED light bars require between 10 and 30 amps, so you will need a power supply to handle at least that amount of current.
After you have cut out the hole for the electrical box, it is time to install it. First, you will need to hold the electrical box in place and trace its outline with a pencil. Once you have traced the outline of the box, you will need to cut out that section of drywall. You can use a utility knife or a drywall saw to do this. Make sure that you cut the hole accurately so that the electrical box will fit snugly in the hole.
Step 3: Pick the Resistor
Now that you have chosen your LED light bar, it is time to choose the resistor. The resistor will be used to protect the LED light bar from voltage spikes and regulate the amount of current that flows through it. To determine which resistor you need, you will need to know the wattage of your LED light bar and your vehicle’s voltage. You can usually find the wattage and voltage on the light bar or in the product description online.
Once you have these figures, use a resistor calculator to determine the resistor’s value. Enter the wattage of your LED light bar and your vehicle’s voltage into the calculator, and it will provide you with a list of resistor values to choose from.
Step 4: Mount the Bar
Now that the light bar is mounted, it is time to wire it up. This is a relatively simple process, but it is important to take your time and do it correctly. First, locate the positive and negative terminals on the light bar. They will be marked with + and – symbols. Next, find a spot on the vehicle’s chassis that is metal and clean. This will be where you will mount the ground wire. Finally, use a self-tapping screw to secure the wire in place.
Now, take the positive wire and run it to the switch. You can do this a few different ways, but the easiest is to tuck it behind the dash and run it to the switch. Once the wire is in place, connect it to the switch and tighten the screw.
Finally, take the negative wire and run it to the battery. Again, you can do this a few different ways, but the easiest is to run it under the hood and attach it to a metal part of the vehicle’s chassis. Once the wire is in place, secure it with a self-tapping screw.
Step 5: Disconnect Negative Terminal
Now, you will need to disconnect the negative terminal on your battery. This can be done by loosening the bolt holding it in place with a socket wrench. Once it is loose, you can pull the cable off the battery. Be careful not to let it touch anything metal, as this could cause a spark and potentially start a fire.
Step 6: Mount the Switch
La prochaine étape consiste à monter l’interrupteur. Cela se fait en perçant un trou à l’endroit désiré et en utilisant une vis autotaraudeuse pour le fixer en place. Ensuite, les deux fils de l’interrupteur (un noir et un rouge) sont passés à travers le trou et connectés aux bornes correspondantes à l’arrière de l’interrupteur.
Step 7: Connect Your Two Harnesses
Now, it’s time to connect your two harnesses. This is a pretty simple process – all you need to match up the colors and then twist them together. Be sure to do a thorough job checking for any frays or breaks in the wiring, as these could lead to problems down the road.
Step 8: Get Your System Ready
If you have not done so already, now is a good time to test your system to ensure everything is working properly. With the led light bar still disconnected, turn on your ignition switch and turn on your headlights. If your headlights come on, then your system is probably working fine. If they do not, then you will need to troubleshoot the problem.
If everything is working properly, reattach the led light bar to your vehicle. Be sure to tighten all of the screws and bolts to ensure that it is securely attached. Then test your system again, this time with the light bar connected. If everything is still working properly, you are ready to hit the road!
Step 9: Get a Professional Help
Si vous voulez installer une barre de feux sur votre voiture mais ne savez pas comment l’installer, vous pouvez le faire installer par un professionnel. Assurez-vous simplement de bien lui expliquer ce que vous voulez qu’il soit fait pour éviter toute confusion.
Wiring a led light bar without a relay can be tricky, but it is doable. By following the steps outlined in this article, you should be able to get it done without any problems. Just be sure to take your time and go slow, and you should be good to go!

Can You Use a Light Bar Without A Relay
A relay is an electrical switch that opens and closes a circuit. It can turn on and off high-power devices like headlights, fog lights, or a light bar. Some people choose to wire their light bar without a relay because they think it’s more difficult to install. However, this isn’t always the case. Wiring a light bar without a relay is quite simple.
To wire an led light bar without a relay, you’ll need to connect the positive lead from the light bar to the positive terminal on your battery. Then, connect the negative lead from the light bar to a ground point on your vehicle. Finally, use a switch to turn the light bar on and off.

Frequently Asked Question
Can You Wire Led Light Bar Directly to Battery?
Yes, you can wire a led light bar directly to a battery, but it is not recommended. A relay should always be used when wiring a led light bar to a battery to prevent damage to the light bar and the battery. Can you wire a LED light bar to your headlights?
Is a Relay Necessary for Led Lights?
A relay is not necessary for LED lights, but it can be helpful. A relay is an electrical switch that can be activated by a low-power signal, such as the one sent by an LED light. This can help you avoid using a high-power switch to turn on your LED lights.
Can You Wire Led Lights To A Car Battery?
Yes, it is possible to wire LED lights to a car battery. However, you will need to use a relay, as the car battery will not provide enough power to run the LEDs directly.
Why Does My Led Light Bar Have 3 Wires?
The three wires are for the power, ground, and switch. The power wire should be connected to a 12-volt power source, the ground wire should be connected to the ground, and the switch wire should be connected to the switch.
