I gave up and went back to standard lamps, I got sick of removing bumper every month as either a lamp or ballast died.
I've had the xenonsonline premium ballast kit on for over 2 years, still going strong and no issues.....
had some on my BMW and it was the worst thing I ever did, looked amazing in the dark but like mentioned above always had to replace bulbs / ballasts for various reasons.
Get some from theretrofit source 5years genuine waranty on xb35 ballasts. Ballast and 2 on bulbs. And they are relly next to OEM... If you have projector headlight afcorse.. Sent from my LG-D855 using Tapatalk
