Can someone please explain the difference between xenon and bi-xenon lights? Thanks.

Xenons are only the dipped beam, with halogens as main beam.

Bi-xenons are both dipped and main beam from the same unit (uses a shutter to cut-off beam for dipped). Still have halogen as supplementary mains and for the flash function.
 
p.s.

"bixenon simply means that your xenon bulb is used for both high and low beam. When you hit the hi-beam switch two things happen: 1) a high beam hallogen bulb lights up 2) Your regular lowbeam xenon bulb gets a lot brighter. Why does it "get brighter"? Because there's a mechanical part that opens up the lens of the lowbeam projector completely, allowing all the light to reflect. In "lowbeam" mode, this mechanical part is always down and restricts the amount of light that comes out.

bixenons headlight assemblies are also clear, project the light better and look sexy. I got me some"
