I was looking and the Xtec series has 5 year warrenty on it. It priced not too bad for the 6000k. I just want to know if any one has used them or not or which would be the best HID conversion kit. Also if i don't switch to HID I wanted to get the Philps Bluevision I hear they are good. If i do switch to the Bluevison anyone have some detailed instructions on how to replace the lowbeam bulbs.
