LEDs are an excellent choice for your home, business, or car because they’re more efficient than regular light bulbs. They also have lower power consumption which will help you save on electricity bills!
If you’re planning on installing LED units by yourself, you must understand everything about led light bar wiring. Believe it or not, many people often overlook this area because they believe it to be confusing.
So, This guide will teach you everything you need to know about LED light bar wiring, including the different purposes of each type of wire.
Basics About Wiring
There are two types of LED light bars: those that function as headlights and those that function as taillights. Each type is wired differently.
One Wire LED Light Bar
it has a single-function light, and the ground (-) goes through the bottom of the housing. In this case, one wire (which could be white, black, or red) will act as positive (+).
Two Wired LED Light Bar
Finally, there is two-wired lighting. These are also single-function units; however, most wires for this type of lighting will be black and white. The black wire is typically positive, while the white wire is usually ground (-).
3-Wire LED Light Bar
These wires are multi-functional light wires, come in red, black, and white colors, and have a different purpose
Black- Second Positive
White – Ground
you can use this wired unit in any application you want to use or suited for your need. Suppose you can use Proof for brake and blinker or running and brake- whatever is best for you.
Installing a 3-wired LED light bar is easy and only takes a few minutes. If you want the light to function as a brake and blinker, here’s how you should wire it.
First, connect the black wire from the light to the positive brake light wire on the car. Then, connect the red LED wire to the positive blinker wire on the vehicle, which originates from the flasher relay.
How to Tell Positive and Negative Wires
If you’re not confident about your skills with three-wire assemblies, don’t worry. There is an easy way to tell the difference between positive and negative wires, using a 9v battery to test.
To start, find the wire you think is negative and press it against the battery’s negative side. Simultaneously Connect one of the two remaining wires to the positive side of the 9V battery.
No damage will occur if you accidentally connect the LED’s positive to the battery’s positive and negative.
Wiring The Battery
By now, you should have discovered how much voltage is needed for the light bar to run smoothly. This is tricky: you’ll have to solder your battery with a soldering gun.
Many videos online can show you if you don’t know how to solder. This procedure aims to heat up the material to cover a larger surface area.
Once the materials dry, the surfaces will have a permanent bond.
While there are easier ways to connect the wires that don’t require soldering, we found it more convenient and efficient for our needs.
If you have the voltage set correctly and an on-off switch in place, the current should flow without any difficulty, and your LED light bar will turn on without issue. The setup we provided is relatively basic. If you feel confident attempting something more complex, there are many options available to choose from.
Wiring a light bar may not be something you are interested in, but you can follow this guide to understand how to do it.
This guide will help you wire a three-wired assembly, so it is not as mysterious. Avoid issues like short circuits by referring to a 3-wire LED light bar wiring diagram.
