These High/Low HID bulbs come with HID xenon bulb for low beam and halogen bulb for high beam. The Halogen bulb is used for your high beam only and is only used where the state requires a high beam to pass inspection.
Note: the High portion of the High/Low bulb is NOT used for high beam driving as it will never point straight ahead. Its just for passing inspection.
