A Bi-Xenon kit converts bulb models: H13, 9007, and H4 into both low beam and high beam to HID with one single bulb that shifts upward when is switched to high beam. It uses an electromagnet to change the physical position of the HID bulb for the low beam as well as high beam. This moving bulb adjusts the focal length and adjusts light output to a wide angle for high beam, and a tighter more focused light for low beam.
In other words, it upgrades your high and low beam to HID, while a standard hi/lo HID kit will only upgrade the low beam.
