[Q]: Not much different than OEM. I'm actually contemplating returning them. I was expecting a nice hint of blue, but nothing...these are actually quite yellow. Did I get fakes? I don't know...but I know that it was a lot of $ I wasted on these expecting an upgrade. My car is a 2017 BMW M3 with projector headlamps

[Q]: Changing review rating. All of sudden just stopped working. Purchased in December 2017. It's only April 5, 2018 now. For the price I paid, it should have lasted. I don't even know how to contact seller. The window for return came and went.
