Hey has anyone else experienced early color shifting on their cheap eBay HID bulbs after a few months? I currently have 5000K bulbs in my 2001 A6 avant that looked nice at first when I put them on in May 2013 but this past week I noticed that they look lot like the old stock 4300s I had before and not the crisp bright slight bluish-white i'd expect from a 5000K bulb. I wanna know others experiences with these bulbs color shifting after a only a few months. If so chime in
