The indicator LED is really very bright and built stable and truly waterproof, there were in the instrument cluster no error messages. The retrofit is actually pretty good, if it was not the not quite as optimal power supply. Since it pushes only the cable lug on the plastic tongue, where it but lack of strength here. Tip, either you welded the power connection by means of hot glue or take a shrink tube, then the plug should remain subject to extreme vibrations firmly on the connector. Greeting Nicole
