Thanks to its resistor and electronic circuit, you will add approximately 12 watts to the consumption of your bulbs and can also correct certain bugs on your vehicle.

The benefits of the Can-PRO HB3/HB4 unit

Removal of OBD indicators

The Can-PRO OBD error-canceller module HB3/HB4 is one of the best on the market for neutralizing OBD errors linked to low power consumption.

Easy installation

The unit plugs directly in Plug’N’Play between the HB3 or HB4 LED and the original HB3 or HB4 connector of the car. It can be paired with another error-canceller module.

• Lighting restored

With this error-canceller module, regain standard lighting for your vehicle, especially if the high beam mode is experiencing malfunctions (Renault Kangoo, Renault Trafic, Toyota Rav4, etc.).


AGM VISION’s opinion on the Can-PRO HB3/HB4 module

We advise you to install a Can-PRO OBD error-canceller module HB3/HB4 to put an end to error messages that appeared after installing LEDs with a power of 15 to 35 watts. If your errors occur with bulbs with a power of 45 to 55 watts, a slight increase in electrical consumption can also be a good option.


Are the warning lights still on, along with various anomalies? This may be due to electrical instability. In this case, opt for an anti-error module / digital filter "Ultra", a unit suitable for smoothing the electric current. The "Supreme" anti-error module is another solution, as it has Can-PRO and Ultra features with its automatic power regulation system and High Power relay function.


If you have already installed a Can-PRO HB3/HB4 module and OBD errors persist, you can install a second unit in series. Your chances of removing errors from the dashboard will thus be multiplied.
