HIDNY has all the necessary stuff in that kit. There really isn't much difference between the one on ebay and the others. The ebay one just simply is trying to make more money. HIDny is a reputable company and has good product. Several members have bought from them. Yeah you should check it out if its close by. Trust me 6000k is more white then blue, hardly any blue in it at all. Ask one of the guys in the store to show you what 6000k looks like on one of their cars. Plus I believe some BMW's use 6000k as stock color if I'm not mistaken..
