Tags: LED CANbus Decoder

  • Capacitor decoders which transmit by pulse signal, fit to pulse power supplied cars. This decoder can also solve the DRL flicker, demand of power and more error code problem.
  • Easy Installation, all-in-One Design, simply plug and play installation.
  • Suitable for Honda Civic, Nissan Rogue, Nissan Murano, Toyota Camry, Toyota Tacoma, Kia Forte, Ford Escape, etc.
  • Don't use on HID light, this decoder only work on LED headlight. Compatible for most vehicles with CANBUS system.
  • No decoder can successfully decode all models, we cannot guarantee it fixes all problems as car system differs from one to another. If you have any questions, please contact us, we will figure out a solution.


  • Model: H7
  • Voltage: DC 12-14V
  • Package included: 2 x H7 Can bus wiring harness adapter.


When will you need a decoder?

When you install LED headlights into your car and have any of the following problems, you may need a decoder.

  1. Bulb flashing when turned on.
  2. Headlight error displayed.
  3. Bulbs stay illuminated after they are turned off.
  4. Abnormally dim light output. 


  • Solve the demand of power problem

CANBUS system monitor the current in-rush of the light bulb it’s controlling and when it sees a larger amount of current, or a smaller amount of current, than the original bulb it causes a problem. It uses capacitance to smooth out the power demands of the new bulb and helps the system adjust to the aftermarket product.

  • Fit to pulse power supplied cars

Pulse width modulation, PWM, is a technology to reduce the heat value of halogen bulbs, help the bulbs last longer, and save more power while operating. Installing LED headlights into a vehicle with PWM configurations will result in flashing bulbs or bulbs that turn off after a few minutes. The PWM module’s large capacitance will basically store up power to eliminate the pulse and supply to the LED headlights with a constant current.

  • Solve the DRL flicker problem

The idea behind the DRL is a safety feature for daytime driving. It does this by dimming the original halogen bulbs in a few different methods:

    1. Dimming by resistance.
    2. Dimming by PWM.
    3. Dimming by voltage reduction.
