When referring to HID lights on an automobile you can break them into 2 basic types; Xenon and Bi Xenon lights.  Both produce the same result, just two different ways.  Specifically, with one or two different bulbs.

Normal HID lights have two HID bulbs in each headlight.  One is designated to the normal or running lights and the other is for hi beams.  In most vehicles the HID bulb used for the hi beams is angled up towards the horizon for maximum illumination of the road, whereas the normal or running lights are pointed downward towards the road to control the light more effectively.

Bi Xenon headlights do the same exact thing except they only use one bulb.  This has it’s advantages and its disadvantages.  The advantage of one bulb is obvious, you only need to pay for one bulb.  However, the disadvantage is that in order to get one HID light bulb to shine in two directions, up for hi beams and down for normal, you need to use the money saved from the second bulb for making the headlight move.

In HID Bi Xenon headlights there are two ways to achieve the dual direction capability needed to achieve a running light projection angle and a hi beam projection angle.  One way is to have a motor that changes the angle of the HID bulb inside the headlight.  The bulb is fixed down towards the road for normal running lights and when the hi beam is engaged the motor moves the bulb up towards the horizon.  The other way is to have a serious of reflectors that changed position in order to project the light in the needed direction.
