Many luxury cars today come equipped with HID headlights as a standard or an optional add-on. You may have noticed the crisp, bright output and the sharp cut-off line that these lights project and wonder if there can be anything done to swap out your halogen headlights. As a matter of fact, there are HID Conversion Kits from Amazon that you can install onto your car to get HID headlights. HID headlights aren't exclusive to the high-end luxury cars now, since you can get a great look like that without having to pay full sticker price.
