Our decoder can solve the following problems:

• High-frequency LED flicker
  Cause: Some modern vehicles supply power in pulses, but the LED driver is very sensitive to current fluctuations, resulting in slight high-frequency flickering.
• Low-frequency LED flicker
  Cause: The operating wattage does not match the original halogen bulb (typically, LED headlights draw 25–38 W, while original halogens draw 35–55 W).
• Error warning light on dashboard
  Cause: The vehicle computer detects an LED headlight instead of the original part, triggering an error code.
• Only one LED headlight illuminating
  Cause: The vehicle computer detects the LED headlight as non-original equipment and cuts power to that circuit.
