The CAN-BUS system in modern vehicles communicates between electronic control units and monitors, among other things, the vehicle's lighting. When you retrofit LED lights, EXTRA LIGHT or LED ramps The system can interpret the lower power consumption as a broken light bulb and display warning symbols or turn off the light. Here you will find adapters, resistors and interference suppression filters that solve these problems.

CAN-BUS is a network in the vehicle that allows electronic control units to communicate with each other. Among other things, the lighting is continuously monitored — if the power consumption deviates from the expected, the system interprets it as a fault. When you replace a light bulb with an LED, the new bulb typically draws 1-2 W instead of 21-55 W, which almost always triggers an error message on the dashboard.
The solution depends on what you are installing. For simple LED conversion of turn signals or position lights, a load resistor that simulates the load of the bulb is usually sufficient. For auxiliary lights and LED ramps controlled via OBD-II, you need an XBB dongle or similar PowerUnit that retrieves control signals directly from the vehicle computer. For Tesla, there are dedicated adapters that match the respective model year.
When installing LEDs, electromagnetic interference can occur that affects the radio, GPS or other sensors in the car. EMC interference suppression filters are mounted inline on the supply cable and attenuate this interference. Filters are especially needed for larger installations such as several additional lights or LED strips with higher power consumption.
XBB is an OBD-II based system that provides control of aftermarket lights without interfering with the vehicle's regular electrical system. CANM8 provides control current signals for specific functions such as reverse light or high beam signal. RUI is a programming device that allows you to adapt the CANM8 module to different vehicles. Which system you choose depends on the vehicle model, which function you want to control, and installation level.
