Feature:1. Function: Solves problems caused by low current draw when using LED bulbs upgraded from halogen bulbs, preventing OBC, on board computers, warning error codes, vehicle specific Canbus errors, hyper flashing, non flashing, bulb rejection, or bulb burnout indication, etc.2. Load Resistor: Pre wired for direct plug and play use, bypassing wiring such as conventional load resistors. The load resistor will ensure that the LED bulb lights up at full power without failing issues3. Interference Elimination: LED decoders feature highly efficient interference absorption circuitry to eliminate interference and prevent bulb flicker.4. Plug and Play: The LED bulb canbus decoder comes with plug and play AMP connectors, eliminating the need for complicated wiring or connections.5. High Durability: Fully immersive structure, providing 100% water resistant and weatherproof, high durability, and consistently stable quality, even in harsh environmental conditions.Specification:Item Type: H4 LED CANbus DecoderInterchangeable Part Numbers: for Canbus No errorsConnector Type: H4Voltage Range: DC 9-16VRated Voltage: 12VMaximum Current: 3ARated Output Power: 35WApplication: No Error Load Resistor Decoder Canbus for installing aftermarket LED setsFitment: Fit for H4 headlight models .Package List:2 x H4 LED CANbus DecoderNote:Even though this decoder size is compatible with your vehicle, we can't ensure that it will solve all problems as car systems vary.
