These LED anti-flicker error-free (canbus) decoders are a welcome addition to LED headlight conversion kits. Without them, some LED conversion kits may flicker, some may not come on at all, while others will generate a "bulb-out" error. Using anti-flicker error-free (canbus) modules is a safe way of converting a halogen bulb headlight system to LED. LED anti-flicker error-free decoders will not harm your vehicle's computer and will enhance compatibility with all vehicle models, especially JEEP, RAM, BMW, Audi, Mercedes Benz, and VW. 8.0W super decoders are just a 2nd generation of anti-flicker error-free (canbus) decoders designed for 2015+ cars and trucks.
