Choose LED light bars tailored for your truck

To create a perfect lighting system tailored for your truck, you need to consider the following three factors when purchasing a truck LED light bar:

Size:

Select light bars of an appropriate length according to the size of the vehicle, to ensure stable installation and uniform and properly bright illumination.

Work requirement:

You need to evaluate your work lighting needs, such as night construction or off-road driving, and choose truck LED lights with appropriate brightness and light patterns according to your work requirements.

Local Legal Compliance:

You must comply with local regulations regarding the color, brightness, and installation position of lamps to ensure that the light bars are legal and compliant. Otherwise, you will face fines or other penalties from relevant departments.


Installation Steps

Choose the right location

Step 1, determine the optimal installation location for the light bars. Common installation points include the roof or sides. 

Prepare installation tools and materials

Step 2, prepare the necessary tools, such as screwdrivers, wrenches, electric drills, etc. Other required waterproof materials, and electrical circuit materials

Install fixed brackets

Step 3, install dedicated fixed brackets. For roof installation, sucker-type or magnetic suction-type bases are usually used; while for bumper installation, custom brackets may be required.

Connect the power supply

Step 4, connect the power supply.

  • Run wires from the battery or switch box and reach the position where the light bars are located through the inside or outside of the vehicle body.

  • Use waterproof connectors and heat-shrinkable tubes to protect all electrical connection points to prevent short circuits or corrosion.

  • Install fuses of an appropriate specification on the main power line to protect the entire circuit from overload damage.


Install the LED light bars and test

Last step, test the LED light bars. 

First, fix the truck LED lights onto the pre-installed brackets and then connect the power supply wires. 

After done, you need to turn on the light to check whether all the lights are working properly. 

Lastly, make sure that each light can emit light evenly and there is no flickering or abnormal phenomenon. 

Tips: If there is any problem, immediately disconnect the power supply and recheck the connection situation.


Maintenance Points

Regular cleaning

You should regularly wipe the surface of the lamps with a clean and soft cloth. 

Tips: Do not use cleaners containing alcohol or other corrosive ingredients to avoid damaging the lamp housing or sealing materials.


Check electrical connections

Check all electrical connection points at regular intervals to ensure that they are tight and there are no signs of looseness. 

Tips: Pay special attention to whether the waterproof connectors are intact and replace aging components when necessary.


Maintain good grounding

Regularly check the state of the grounding wire to ensure that there is a reliable electrical connection between it and the vehicle body. 

Tips: If a metal vehicle body is used, the contact surface can be polished and conductive paste can be applied to enhance the grounding effect.
