Resistance for H4 LED SET bulbs from the company M-TECH, of Polish origin, equipped with a 320 mm cable, an ideal car accessory that functions as a canceller in the CANBus network, bypassing the command from the brain to prevent false errors and deactivating the malfunction indicator on the dashboard.

The CANBus (Controller Area Network) system is a serial communication protocol between the car's subsystems and the central processor (CPU), which controls the consumption of the bulb during operation and recognizes whether the bulb is burnt out or malfunctioning, notifying the driver with the corresponding warning light. Vehicles equipped with this system encounter false virtual “problems” with replacement LED bulbs due to lower consumption, and thus the canceller, which contains a small resistor, appears to raise the bulb's consumption and “fools” the CANBus into “seeing” the current load it should. In this way, the product allows the installation of LED bulbs without affecting the normal operation of the car at all.

• Cable length: 320 mm.
• Compatible with: H4 LED SET bulbs.

Note: LED bulbs are not included in the package.

Package contains 1 piece.
