I installed aftermarket HID's into my 1996 Contour's low beams. The low beam factory set up was poor from day one. I've owned the car since new. The HID's offer a much better illumination of the road and no one has flashed their lights at me. I only have them in my low beam lights. My high beams are still the factory bulbs and are fine for added illumination. My HID's are 5,000K.
