Non-Adaptive Xenons?

I bought a 2005 325i a couple of weeks ago. Well, I finally found out what options I have. It lists xenons at $700. Are these adaptive or no? They don't seem to swivel left and right. But its my wife's car and I never drive it, so I can only look at it when she pulls away from the driveway.

They are not adaptive, you have bixenons. The adaptives were only available on facelift coupes.

Thanks, Nick. BTW, what is the difference between xenon and bi-xenon?

with single xenon (xenon) your car still uses halogens as the highbeams (99-01 e46s), and with bi-xenons your car uses the xenons as both high and low beam functions(although halogen is still used as flash to pass), I think the bi-xenons are supposed to have better output as a highbeam function versus xenon+halogen.

all xenons have a cutoff shield, behind the projector, that controls (restricts) where the light is spread (to not blind oncoming/and neighboring drivers) With bixenons, when you select highbeams, this cutoff shield is pulled away, releasing unrestricted xenon light.

There are also projector differences, the single xenons use a 2.5" projector while bi-xenons have a 3" projector. And there cutoff is different, most voting that the single xenon has a better cutoff. But the ouput of the bi-xenon projector I think has slightly better (not very noticeable) output.

In a nutshell

Although in terms of low beam output, both the bixenon and regular xenon are almost exactly the same. Bixenons do have a bit higher high beam light output, however.
