The LED anti-flicker error-free (canbus) decoders are a welcome addition to LED headlight conversion kits. Without them, some LED conversion kits may flicker or 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 in any way, and they will enhance LED compatibility with all vehicles, especially JEEP, RAM, BMW, Audi, Mercedes Benz, and VW.
1st generation decoders are used to solve LED flickering issues.
2nd generation super decoders are used to solve LED flickering issues, and "bulb-out" dash warnings.
If the vehicle's headlights are shutting off after upgrading to LEDs you will need to add 50W resistors which boost the power draw mimicking the usage of a halogen bulb.
The anti-flicker decoders will not resolve EMI (electro-magnetic interference), they only stop the LED lights from flickering and the car from displaying a “bulb out” error message on the dash due to the low LED power draw.
