[QUOTE="valkryie, post: 106678, member: 2023"] Thanks Saat for the tehnical write up. Anyway i post a picture of projector headlight with a halogen reflector side by side to better explain myself. [img]http://www.umnitza.com/images/p46c.jpg[/img] The projector is feature on the right side and the normal halogen reflector is on the left side of the headlamp. A Bi-xenon projector does not necessarily mean there are 2 projectors in the headlight unit. The newer bi-xenon projector is [u]a single xenon projector[/u] capable of high and low beam. The high/low beam feature is controlled by a shield or shutter that moves up and down electronically behind the projector lens. Maybe i confused everybody by making everybody think there is a reflector behind the projector lamp. The halogen reflector is retained for beam flash function. You can check out Valeo Bi-xenon projector in [url=http://www.valeo.com/automotive-supplier/Jahia/pid/554]valeo press release[/url] under the valeo xenon projector lightning paragraph. CKD E46 with original halogen reflectors are not capable of having bi-xenon low/high beam projection as the car is not wired for it. So even if buy a bi-xenon projector headlight you will only get a low beam projection. You will need dual projectors. Check out this [url=http://e46fanatics.com/features/feature.php?news_id=48]write-up[/url] for a better understanding on the pro and cons of an HID conversion kit, retrofitting a projector vs getting an OEM projector head light.
