HID in a halogen designed housing is a big no no. HID kits are junk and useless for performance. They are only good if you want a HID appearance.If you want to spend a little more money, HID is also a good option. It gives a lot more lights than regular bulbs and the installation is very easy. You would need to lower your headlight aim a bit though since the lens are not designed for HID.
Spend the money and do it right with using HID oem components (HID projectors and oe ballasts and bulbs)
