To use HID lights properly you need a good projector lamp housing. HID in normal housing will spray the light pattern in everyones eyes and also have to much spread in its pattern. Also be careful picking a projector lamp. A "Cheap" housing usually has black inside the barrel of the projector housing and you will end up loosing the amount of light you should have gained. The projector that says Halogen will not properly pattern a HID light. Another point to remember is the xxK value is a color value not intensity value. The closer you can get to 50K the more "Pure" light it will produce. A true HID has to have a firing voltage and a steady voltage otherwise they will burn out quickly and not give off good light. Some manufacturers make a bulb and label it Xenon and call it HID even though it is a plug and play, not a 20,000 volt plus HID.
I had some on my '01 and made the housing mistake resulting in less light than stock. The HID's in the projector will have a pattern of left of center a few inches lower than the right of center, signs and pedestrians....
