We just did the 1st f30 car in south Florida and It worked great!
We sell the kit for $120.00 and you will have no issues at all!
here is some pics of the fog lights, and we did HID Head Lights and LED City light bulb! Sorry not the best pics yet but it will do!
pretty sure it's not the BALLAST.
It is for sure, if i am understanding right that the bulb is flickering and not staying on.
its takes a bigger ballast with a higher canbus system to make it to work and stay on with no codes.
