Very disappointed with the product. Knowing that it's a BMW genuine product my expectations are really high. I bought this item around end of Nov 2016 and managed to put it on my car around second week of Dec 2016. There's not much change compared to the oem bulbs. It's not that bright during night driving. After a few weeks whilst starting the car, one of the bulbs is already gone... a warning message immediately appeared on the dashboard.
The product is not worth it. I recommend converting to HID where you will immediately see the difference and especially the safety in night driving as it gives you a really bright and crisp vision.
BMW, this product is not worthy of a £40+ price tag.
