Xenon HID Light Bulb Replacement

Those are just a bunch of crap! They're just halogen bulbs that have a blue coating over to make them look like HID's. I have to say that they don't look too bad on a car, but their light output is less than a typical halogen! If good night vision is your goal, buy an HID conversion kit for a few hundred dollars. The difference is night and day, no pun intended.
