Keenso H4 LED Headlight CANbus Decoder, 2 Pack Anti Flickering Error Free Resistor with Plug and Play Design DC 9 to 16V, for H4 LED Headlight Bulb Anti Flicker

• 【Eliminates LED Error Codes and Hyper Flash】Upgrading halogen headlights to LEDs often triggers dashboard warning lights, bulb-out errors, or flashing. This pair of H4 LED CANbus decoders tricks your vehicle’s computer into accepting the lower power draw, solving Canbus errors, bulb rejection, hyper flashing, and non-flashing issues for a trouble-free LED conversion.
• 【Plug-and-Play Pre-Wired Decoder – No Splicing Required】Traditional load resistors require cutting and taping into factory wiring, risking damage and voiding warranties. This decoder comes pre-wired with AMP connectors for direct connection, eliminating complicated wiring and making installation clean and simple.
• 【High-Efficiency Interference Absorption Prevents Flickering】LED bulbs can flicker or create due to electrical noise. Built with advanced interference absorption circuitry, this decoder stabilizes the current, ensuring your LED bulbs light at full power without flickering or unwanted electronic noise.
• 【Fully Sealed and Weatherproof Build】Under-hood moisture, road salt, and temperature swings destroy resistors and decoders. The fully immersive, sealed structure provides 100% water and weather resistance, delivering high durability and consistent quality even in harsh environmental conditions.
• 【Specifically Designed for H4 Headlight LED Retrofit】 decoders may not fit your bulb’s connector or work with your vehicle’s Canbus system. This H4-specific decoder is tailored for 12V DC systems (9‑16V range, 35W), compatible with most vehicles using H4 headlight sockets. However, car systems vary, so compatibility cannot be guaranteed for every model—please check your vehicle’s requirements before purchase.

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 issues 3. 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.
