I had this same problem. Not the fuse. It's the little black electronic gizmo that drives the bulb. They call it a driver. (It appears to be a voltage booster, from 12v to 18v). Mine lasted about a month. Caused all kinds of problems. After I got a replacement driver, it still wouldn't work. The car's ECU can tell there's a problem and shuts it down. Has to be reset by the dealer. Too bad, it looked a lot better, but I'm not going to risk these problems again.
