What exactly are bi-xenon headlights?

Question:
I am thinking they are high and low beam xenon headlights. However, I was confused by the repair shop manager who told me that there is no such thing as high beam xenons. I would think the repair shop manager would know what he is talking about. Can someone clarify that for me?

Essentially, you are both correct. A "bi-xenon" headlight assembly has only one bulb that's used both BOTH high beam a low beam. A shutter / reflector is moved into the beam path when low-beam is selected to reduce the beam intensity and alter the beam path.

Why do some people think it's better to back your car into a space?

A traditional halogen light with two use would have two actual filaments, one for high beam and one for low beam, or two separate bulbs in the same assembly.
