Why We Need LED Bulb CAN bus Decoder?

Since LED headlights work differently than original halogen lamps, the feedback signal from the LED headlights may not be detected by the onboard computer after replacing the LED bulbs, resulting in an error message on the instrument panel. Therefore, it is necessary to install an LED decoder to solve the fault alarm caused by retrofitting LED headlights.

Built-in powerful can-bus chip, compatible with 95% of onboard computer systems on the market.

The LED bulb decoder has an all-in-one design, just connect the wire with the provided connector, plug, and play.

Problem Solved:

  1. Headlights failure message on the dashboard;
  2. High beam failure message on the dashboard;
  3. LED headlights, hyper-flashing or flickering;
  4. The engine stops working when turning on the LED headlights;
  5. The LED Headlights stop working When the engine is ignited;
  6. LED headlights automatically turn off after lighting up for a few minutes.
  7. Radio interference and buzzes

Warm Tips:

2. Since CAN bus decoders can get very hot while working, it is best to mount them in a ventilated area and on heat-resistant/non-burning metal for longer life.

3. If you are not sure which LED CAN bus decoder to buy, please feel free to contact our customer service for support.

Work well

Actually with another brand of lights I had to use additional decoders, but with the N67EP Series | H11 H8 H9 LED Headlight Bulbs Extremely Brighter Light 140W 32000LM | 2 Bulbs, the decoders that came with them worked, and I did not need to use Anti-Flicker LED Canbus Decoder for H11 Light Bulbs High Performance Resistor Warning Canceler.
It was a very pleasant surprise.

Tom Pokorny
Absolutely necessary for my 2007 Jeep

I have improved my older Jeeps mounting LED bulbs for both low and high beams. As this step worked as simple swap without any problem on really old one WJ, the newer XK with CAN-BUS had very strange "flickering" issue, not only when lights set on, but also with key turned off and car locked.
I did some internet "investigation" about "anti-flickering" solutions and found the Novsight system sophisticated and interesting for me. Delivery to the Europe was perfectly all right, the mounting as well. Only one comment - the original car socket has some "rabbet" for one-way insert only, the decoder not, but it is evidently no problem.
Using these decoders are my lights once again standard functioning and I am enjoying bright light of LEDs. After ca 3.000 km I cannot evaluate their working life for the present, but as for functionality I can warmly recommend it.

Dear Tom,
Hi, thank you for your detailed review, we really appreciate it.
This review is also of great reference significance to other customers.
Thanks again for your review, all the best.
