Actually, "bizenon" is more a marketing concept and the litronics could easily fit the definition.

HID burners are not good for high beams because of their delay in coming to full brightness. Mercedes, for one example, used the bizenon term to describe a process where a moveable metal shield adjusted between high and low positions to provide both beams from the same bulb/burner.

In litronic, a halogen bulb comes on to provide a quick high beam but also the level of the low beam hid projector is mechanically adjusted higher to supplement. It's obviously not as instantaneous as the halogen bulb. Pretty much the same result as bizenon.
