Features: 1. Function: Addresses issues caused by low current draw when upgrading from halogen bulbs to LED bulbs, helping prevent onboard computer errors, CANbus errors, hyper flashing, non-flashing, bulb rejection, or false bulb burnout warnings. 2. Load Resistor: Pre-wired for direct plug-and-play installation, eliminating the need for additional wiring typically required with standard load resistors. Ensures LED bulbs operate at full brightness without compatibility issues. 3. Interference Elimination: Equipped with efficient noise suppression circuitry to reduce electrical interference and prevent flickering. 4. Plug and Play: Includes AMP connectors for easy installation without complex wiring or modifications. 5. High Durability: Fully encapsulated design provides 100% waterproof and weatherproof protection, ensuring reliable performance and long-term stability in harsh conditions.
