LED Canbus Decoder-Anti Flickering Resistor-3 Solutions for LED Flicker in 2024

After adding LED bulbs, have you encountered radio interference, dashboard issues, or bulb flickering? We refer to these as decoding issues altogether. Next, I will discuss why decoding can be difficult, the different types of decoders, and the pros and cons of each.

The relationships between CANbus and headlights must first be understood.

CANbus, also known as Controller Area Network bus, enables devices and microcontrollers to interact with one another's applications without needing a host computer. To briefly, CANbus will assess the various automotive components' operational state. To ascertain whether the lightbulb is functioning, the CANbus system will measure the circuit's resistance and the light's pulse signal.

The LED light bulb has a low voltage. This voltage triggers the CANbus system. The CANbus system turns on the warning light. This happens when you replace a halogen light with an LED one.

There are three different kinds of decoders available:

Resistor, Capacitor, and Mixed type are used with both of them.

1-Resistor decoders

Conventional halogen bulbs typically consume less than 55 watts. LED requires only 15–35 Watts, which makes it more power-efficient. That may indicate that your light's work cycle has ended, according to CANbus. A resistor might increase power consumption, fool the CANbus, and stop the led headlight flicker.

A resistor's advantages include being inexpensive, simple to use, and nearly always functional. The resistor has the drawback of producing a lot of heat. It must be installed on the metal components and kept apart from the rubber ones.

Pros: Low price, Easy to use, Reliable

Cons: High generation

2-Capacitor decoders

High-power LED car bulbs under 45–55 watts often flicker due to the pulse width modulation system from the CANbus. Flattening out the volt turbulence with a capacitor in this case helps lessen the blinking issue. Capacitors, however, are limited to specific automobile modules. Thus, they might not be able to resolve the issue.

Pros: Reduce the blinking problem

Cons: Only work in some car modules

3-Combination decoders

The combination decoder is about to appear. A circuit board, a resistor, and a capacitor are typically used in combination decoders. The circuit board was designed to recognize the CANbus protocol to enable plug-and-play functionality. This kind of decoder can resolve almost 90% of flicker issues.

It was simple to use this decoder. It offers the same signal feedback as a halogen lightbulb, produces little heat, inspects the onboard computer's pulse signal, and delivers steady power output with less safety risk. The price difference with the other varieties is the sole drawback.

Pros: Plug and play, Same signal feedback, Low-heat generation, Pulse signal inspection, Stable power output

Cons: High Prices

After reading the material above, everyone knows how decoding challenges are created and the three primary categories of decoders. We suggest that you use this combo decoder, the Aventuraeoffroad CB-6. With its all-in-one design, you only have to plug it in and connect the wire to the supplied connector. Robust built-in can-bus chip that works with 95% of the market's onboard computer systems.
