About

C20 CANbus LED Decoder & Anti-Flicker Resistors – Essential Accessories for LED Headlight Upgrades Hawkglow’s C20 CANbus decoders and anti-flicker resistors are precision-engineered accessories designed to ensure full compatibility between aftermarket LED headlight bulbs and modern vehicle electrical systems. When upgrading from factory halogen to LED bulbs, many vehicles equipped with CANbus-based electrical architectures will detect the lower power draw of LED technology as a fault condition — triggering dashboard warning lights, error codes, or hyperflash turn signal behavior. The C20 decoder resolves these issues at the source, delivering a seamless, error-free LED upgrade experience. Technical Advantages Eliminates Dashboard Error Codes: Precisely calibrated load resistors simulate the electrical signature of factory halogen bulbs, preventing the vehicle’s CANbus system from registering LED bulbs as a fault condition. Resolves Hyperflash & Turn Signal Flicker: Corrects the rapid-flash behavior that occurs when LED turn signal bulbs are detected as burned-out by the vehicle’s flasher relay — restoring normal, legal turn signal operation. Suppresses Warning Light Activation: Prevents “Bulb Out” or “Check Lamp” warning indicators from illuminating on the instrument cluster following an LED headlight bulb installation. Plug-and-Play Installation: Engineered for direct inline installation with no cutting, splicing, or wiring modifications required. Compatible with all major LED headlight bulb sizes including H11, 9005, 9006, H4, H7, and H13. Thermal Management: Constructed with heat-dissipating materials to ensure stable, long-term operation under continuous electrical load without degradation. 2-Year Warranty: Backed by Hawkglow’s comprehensive warranty and professional technical support team. Recommended Use: The C20 decoder is strongly recommended for all vehicles equipped with CANbus electrical systems when installing aftermarket LED headlight bulbs . If
