Tested quality and reliability! Le produit SUPREME TRUCK ANTI ERROR MODULE H4 was tested in our garage and we use it frequently for our customers.

Satisfaction guaranteed!

High quality for this anti-error truck module.

The H4 Truck Supreme anti-error module is one of the best units currently available. Its all-in-one intelligent system removes 96% of OBD errors and automatically adjusts your power consumption to 55 w, the consumption value of your original bulb. 


This H4 Supreme anti-error module reduces flashes by 80% to 100% at startup and while driving. It offers an ultra-efficient LED anti-flicker system. In its extreme version, it acts as a high-power relay. Thus, you benefit from improved electrical connections and premium insulation against all electrical interference. Say goodbye to overheating problems, power cuts, voltage drops or spikes! 


We recommend the H4 Truck Supreme anti-error unit for all multiplexed trucks or those equipped with an onboard electronic system. It is also recommended for very high-end vehicles (Mercedes and others). Choose this safe module, guaranteed harmless for your electronic control units!

Mounting of the enclosure only without electrical harness

With this installation method, the H4 Truck Supreme anti-error module behaves like a classic anti-error unit:

  • Its ultra-powerful resistor system allows you to increase electrical consumption by about 5 watts.
  • Its two capacitors reduce the number of light flashes.


Plug the module in Plug'N Play between your H4 LED bulb and the vehicle's original H4 socket. If you do not want to spend too much time on the installation, this method is sufficient in most cases. 


However, with this installation mode, the emitted resistance may be slightly too weak, which can cause a warning light to remain on. In this case, we advise you to install an additional module (type Can-PRO 24V H4). Connect it in series to increase your chances of eliminating the OBD error. You can also choose the second installation method.

Assembly with electrical wiring on battery

The Truck Suprême H4 anti-error module, connected to the battery, operates with two distinct electrical circuits. The first provides high-quality, stable power supply with no disturbance or voltage fluctuation. The second is dedicated to electronic control and only processes signals for OBD error detection.


This installation of the Truck Suprême H4 anti-error module on the battery allows you to benefit from all functionalities in extreme mode:

  • An intelligent automatic power adaptation system. This device prevents 96% of OBD errors and maintains your LED power between 50 watts and 55 watts in real time.
  • A wide power range (from 5 to 75 watts) with regulation at the same value, regardless of the LED power and the number of integrated anti-error modules.
  • Protection of your embedded electrical system and extension of the lifespan of your LED or Xenon kits with one of the most reliable devices.


Supreme Truck Box: what are the advantages?

The Truck Suprême H4 anti-error module erases 96% of OBD error messages on your dashboard. You reduce by 80 to 100% the light flashes occurring at startup after installing LEDs on your multiplexed vehicle. No more radio interference and extended LED lifespan!


The Truck Suprême H4 anti-error module restores a continuous electrical supply without variation in intensity or voltage for older vehicles powered by alternating current. Is the high beam mode malfunctioning? Only one out of two LEDs lights up after installation? Does one of your bulbs turn off when driving? This Truck Suprême H4 box is ideal for countering electrical instabilities and regaining normal lighting operation.

When installing LEDs, it may happen that your vehicle's electrical unit overheats due to too much resistance. The Truck Suprême H4 anti-error module protects the truck's different components against these short circuits and electronic failures.


If you choose an installation directly on the battery, the power will be adapted to the operating value of your original bulb. For your information, the Truck Suprême anti-error module works for a Xenon installation with connection to the ballast.
