What is a “single beam” and a “dual beam” / “bi-xenon” HID kit?
A “single beam” kit fits the same bulb socket, but will only work as a low beam with no high beam functionality. A “dual beam” or “bi-xenon” kit has a separate high beam function. Some vehicles use a single bulb with two filaments built into the bulb which has both low and high beam function built into one bulb. For these vehicles, you will lose the high beam functions on your headlights when installing a “single beam” kit. However, the adjustment in the bulb capsule will compensate for the loss of high beam, and it will be alot brighter than your halogen high beam and yet not blinding for other drivers.
