Richard is correct, you will need to replace the stock housings with projector housings if you want to upgrade to HID. When replacing with HID or LED do your research, there are a lot of cheap (China) products being sold that have problems and you won't be happy with them. A quality product will have a beam pattern that makes the most effective use of the light without blinding oncoming drivers, won't flicker, and will last at least as long as what you are replacing.
