Here is a little basic knowledge of HID and HID lookalikes.
HID Lights that you see in most BMW 3, 5, 7, and X series have an AUTO LEVELING system that shifts the projector to adjust to the road (Like Porshe, Lexus LS430, new GS430, Ferrari, M/B, Audi, S2000 Honda). Just buying a Philips HID or any other aftermarket HID kit will not give you that flickering of color you see when the car is coming towards you. That flickering is produces when the bulb is moving up and down with the auto leveling system.

You are correct to a point. But you must understand that because the projector is pitching much more than a non leveling car you will see more of the prism effect, thus giving a much more noticable shift in light coloration. You can compair this by looking at an Acura 3.2TL. 3.2CL or 3.5RL. They do not have a auto leveling system, they just look really blue and purple at all times. because they are not shifting up and down, thus you are not seeing the outer edges of the light patern.

I see what you are saying TealLexusSc400. I think we both have a point on why different HID systems look as they do. I don't want to start an argument - and I know you weren't either

Autolevelling adjusts the pitch of the free-form reflector to guide the body of light up and down. This system has little to do with the existance of color flicker. It does make it more noticeable on rough roads, but even when an Audi is driving down a smooth, flat, level road, it will appear purple from certain distances and angles regardless of autolevelling. All projector optics have the capability to produce flicker, the S2000 can throw off deep yellow and red color as well as purple, green, and blue because it's optics are very uniquely mounted, which make them nearly impossible to retrofit

When i'm riding with my friend in his S2000 you can see the leveling system working, even on a level road. My girlfriend has a new 540 and you can see her lights shifting as well while driving. The only time I see them flicker is at an angle or when they are leveling.

I was just riding home when I spotted someone far ahead of me with HID lighting. It was a 7 series. It's lights were purple, when I was way behind it, when I was beside it, and when I saw it in my rearview mirror when she was directly behind me. Now I'm talking about SUPER purple, b/c the ground and everything else was reallllly purple. This makes me highly doubt that ALL OEM HID equipped cars come standard with 4100K bulbs. And I seriously doubt that the bulbs were changed, or that it was an aftermarket kit b/c the lady looked like she was in her mid 60's. And I know about the optics, and yada yada, but this was just realllly purple. Hopefully if I get the autolamp 6000K's, THAT'S the kind of purple it'll be.

I too have seen the BMW bi-xenon HIDs from a parked, stationary 745iL. They are white from dead on, not purple. Step inside a 745iL for yourself, you'll see it light up a WHITE road. Of course the HIDs are not going to appear white from behind you because that would mean they are aimed too high. If another motorist can see the direct light from a projector that is supposed to be projected onto the road, that means there is no autolevelling and the aiming screws are set too high.

ok my question is, would the Aiming screws on the headlights of auto-leveling headlights change the level of the headlights? or does the auto-leveling always keep it in the middle no matter where the screws aim the lights?

Now I've seen them on a new 3 series, and they were purple when they were behind me, but the light output on the ground SUCKED. They didn't put much light on the ground, for OEM hid's. But this 7 series was lighting up evvvvvvvvvverything, and it was a darkish purple. NOOOOOOOOO white at all. So maybe it was just an old lady with some style, and put some K2's or Phillips ultinon's on
