Canbus proof LED lighting, what is it?

An increasingly common concept, the CAN-bus (Controller Area Network). A standard for serial data transmission between various components. The CAN-bus is specially designed for environments with a lot of electromagnetic interference. At TRALERT® we have several canbus proof lights, which eliminate the interference caused by LED lighting. In this article, we explain more about the can-bus system, among other things. In addition, we will give you more information on the Can bus resistance, operation canbus and can-bus system explanation.

CAN-bus system explanation

How does canbus work? The on-board computers, which are mainly used in newer cars, normally ensure that the driver of the vehicle is informed of any interference. For example, if the light is faulty. Actually, the CAN-bus system measures the current draw of a specific light. When the bulb is faulty, it will no longer draw current and you will be notified that the light is faulty. In short, this is how canbus works. However, this need not always be the case.

CAN-bus system explanation for LED lighting

When you use LED lighting on your vehicle. Then you know from the outset that this energy-efficient light requires less energy than the original bulb to give maximum light output. Due to this small decrease in energy, the canbus system is fooled, so to speak, and the canbus system issues a fault message.

Canbus proof LED lighting

To solve this deception on the on-board computer, there are several possibilities. For example, it is possible to place resistors on your vehicle to fix error messages on the dashboard, canbus messages or an indicator. Often, these error messages can be solved easily.

Besides resistors, TRALERT® also offers canbus proof LED lights, where the remedy for this interference is already built into the light. These LED lights are called CAN-bus proof LED lighting.

Advantages of built-in Canbus proof LED lighting

If the Controller Area Network is already built into the LED lighting, this is a good addition. For LED rear lights for trailers, as well as for truck and trailer, the CANbus proof solution is a real added value. As a dealer, we can imagine that potential buyers often ask questions about solving Canbus problems. If the LED lighting is already equipped with a canbus proof solution as standard, you will immediately avoid these questions.

What is canbus lighting?

If the on-board computer and/or display in your vehicle's dashboard show a message that a specific light is broken, it means that your vehicle has a canbus system. The can-bus system therefore measures the power consumption of a specific light. So a broken lamp no longer draws any current and you will therefore get the message of a defective light.

Is this solution also suitable for 12V trailers?

In the TRALERT® product range we have a number of types of LED lighting for trailers with canbus proof solutions. Especially for the trailer sector, this technology is a real addition. Another solution is the use of CAN-bus resistance. Our product range includes several resistors that provide the solution for the error message on the dashboard.

Which CAN-bus proof LED light is most suitable for my vehicle?

If you are looking for a CAN-bus proof LED rear light, we recommend you take a look at theVC-2701B5CAN. It fits well on trailers, semi-trailers and small (horse)trailers.
