What is Bi Xenon HID?

Bi-Xenon Headlights refers to HID (High Intensity Discharge) Xenon headlights that offer both low (dipped) and high (main) beam lighting from a dual headlight system (as opposed to a quad headlight system).
A bi-xenon system eliminates the need for a separate halogen high beam bulb/lens by either moving the xenon bulb within the lens or by moving a shield up or down in front of the bulb (depending on the reflector design) to allow light to escape from the lens in a different pattern.
A bi-xenon system typically features dynamic headlight leveling and on some vehicles direction adjustability.
