Works as advertised so far. Better then spending 300-600 bux. Perfect for a fraction of the costMuch cheaper solution to oem and does the same job. Exact product that is in my vehicle. I purchased this from this company. My drivers side light would flicker a few times when I first started my '08 335i sedan then just remain out. This ballast fixed my issue.
