Lightbar Harness

Lightbar Harness, or LED light bar harness, is a special wiring assembly used to connect LED light bars to the vehicle power system. It safely and efficiently connects LED light bars to the vehicle power supply through plugs, cables, relays, fuses and switches, provides a stable power supply and ensures the normal operation of the light bar. The harness is customized according to the power, working voltage and purpose of the light bar, and is widely used in the lighting systems of off-road vehicles, trucks, engineering vehicles, agricultural machinery, etc.

In a complex circuit environment, the Lightbar Harness not only undertakes the function of power transmission, but also helps circuit protection and installation convenience. It is an indispensable component of an efficient lighting system.

Lightbar Harness


Material:

Wire material: pure copper wire core, the diameter is usually 1.5mm² to 4mm², the conductivity is more than 97%, and the resistance is less than 0.02Ω/m.

Sheath material: PVC, PE or silicone sheath, with wear resistance, heat resistance and UV resistance.

Connector type: DT connector, waterproof plug, voltage resistance 1000V, plug and unplug life more than 500 times.

Relay parameters: 12V/40A or 24V/30A, response time<10ms, 100="" service="" life="" more="" than="">

Operating temperature range: -40℃ to +125℃, meeting the needs of high temperature engine compartment and cold mountainous areas.

Fuse specifications: standard ATO plug-in fuse, 10A 15A 20A 30A optional, easy to replace.


Application:

Off-road lighting system

With LED spotlights and long strip lights, it provides a wide range of strong light illumination for night off-road and ensures clear driving vision.


Engineering and agricultural vehicle lighting

Engineering vehicles, tractors, excavators, harvesters, etc. are equipped with LED work lights, which are powered and controlled by wiring harnesses to meet the lighting needs of night operations.


Emergency rescue vehicles

Such as police cars, fire trucks, and ambulances use LED warning lights, which are centrally controlled by wiring harnesses to achieve fast opening, closing and flashing functions.


Ship and outdoor equipment lighting

In fishing boats, campers, RVs and other equipment, it provides stable power transmission and control functions to ensure stable operation of the lighting system.


Decoration and display purposes

Used in scenes such as auto shows, modification displays, and interior and exterior atmosphere lights of cars, it ensures unified power supply control of multiple sets of lamps and improves the modification effect.


Features:

High current carrying capacity: high-quality cables use 14AWG, 12 AWG or thicker wires, support a maximum power output of more than 300W, and the current carrying range can reach 30A to 40A, which is suitable for high-power LED light strips.


Equipped with relays and fuses: built-in standard 40A relays and 15A, 30A and other specifications of fuses, effectively prevent current overload and short circuit problems, and improve power safety.


Waterproof and dustproof design: Most wiring harness connectors and switches are sealed with IP65 or above, which can withstand high-pressure water flushing, mud and dust, and adapt to harsh outdoor environments.


Plug-and-play structure: The wiring harness is equipped with standardized plugs, such as DT connectors, Deutsch connectors or customized connectors, which supports quick plug-in and unplugging, saves wiring time and improves installation efficiency.


Supports multiple control methods: Configure multiple modes such as mechanical switch, remote switch, Bluetooth control or APP control to meet the diverse control needs of different car owners.


Flexible and customizable wire length: The standard length of the wiring harness is commonly 3 meters, 5 meters, and 8 meters, which can be customized according to the vehicle size and wiring path to adapt to different types of vehicles.


Advantages:

Improve circuit safety: By integrating relays and fuses, it can quickly break the circuit to protect the device when the current is abnormal, avoid burning the LED light bar or battery system, and reduce the risk of electrical failure.


Extend equipment life: Stable voltage output and anti-interference ability help to extend the life of the light bar. Data shows that the life of the light bar using a high-quality wiring harness system can be increased by up to 20%.


Improve installation efficiency: The plug-and-play wiring structure allows non-professionals to complete the installation without additional welding or wiring, and the average installation time is less than 15 minutes.


Strong compatibility: It is compatible with various 12V/24V power supply systems, whether it is a pickup truck, UTV, SUV, ATV, engineering vehicle, or motorcycle, and can be used in a wide range of applications.


Adapt to complex environments: It has a wide temperature range (-40℃ to +125℃), is oil-resistant, shock-proof, and corrosion-resistant, and is suitable for use in harsh conditions such as crossing, exploration, construction sites, and extreme cold and high temperatures.


Functions can be expanded on demand: Flash control modules, dual-channel outputs, remote control, voltage display and other functional modules can be added, which is highly flexible and meets personalized needs.


FAQ:

Can the Lightbar Harness connect multiple light bars?

Yes, provided that the total power output capacity of the harness is sufficient. For example, a harness equipped with a 40A relay can connect two 120W light bars at the same time, depending on whether the total current load exceeds the rated value.


Are the harnesses used for 12V and 24V systems the same?

Answer: Most harnesses support 12V and 24V, but make sure that accessories such as relays and switches are marked to support dual voltage operation. If not specified, please use the specified voltage model.


Does the Lightbar Harness require professional installation?

No. High-quality wiring harnesses are plug-and-play designs. Users only need to connect the positive and negative poles, power supply, relay and light bar according to the instructions to complete the installation.


What if the wiring harness is not long enough?

You can choose a model with an extension cord or customize a longer version. Most manufacturers support customized cable lengths, such as 5 meters, 8 meters, 10 meters, and up to 15 meters.


What are the effects of the wiring harness not being waterproof?

Unwaterproofed wiring harnesses are prone to short circuits, rust and even spark risks in humid environments. It is recommended to choose IP65 or above products, which are safer and more reliable when used outdoors, in rainy days, and in wading off-road.
