What John said. Too cheap to fuck around. I helped a neighbor with HID issues recently, and after replacing one part, then the other, it seemed like they were causing each other to fail. No idea if that's possible, but that was the gut feeling. He's back on regular bulbs now.
I have a set of LEDs for the XX, haven't tested them yet. If that would interest you, Oscar and I can fire one up with a whisky and a cigar in the garage later and give a driveway review.
