Seems like a pretty good value here. Of course usually this comes with a sacrifice in quality. Anyone have experience with DDM's HID replacement bulbs? Mine are going out soon and I need replacements. Stock is like 4300K, I am thinking about 6000K for whatever replacements I opt for. At $120 a piece, the OEM bulbs aren't exactly affordable (that's the price over at KefferVWParts.com).
