Scott,
You have been given a lot of excellent information here. Please do not stick HID bulbs in your standard headlights. I tried that and drove oncoming drivers crazy. I upgraded my headlights to HID by grafting Nissan Murano HID projector headlight assemblies onto the back of 7" round headlight shells. It was a lot of work, but was relatively cheap compared to the units that you can buy. I also use a soft clear shield to protect them and they look ok. I get a really sharp cutoff with the low beams and powerful long range high beam when the shutter opens. I have also added HID driving lights for the wide open back roads that we run on our rallies.
