I had Xenon on my E46 and miss them. I made some steps for an eventual conversion and got even blasted by some morons in another section for just considering something else than OEM, only asking for references. As much as I like the Xenon in the night, I much prefer the look of the halogen headlamps on day time.

(nonetheless it is great to have real alternatives to OEM. Good find.)
