However, when it comes to the performance of bi-xenon headlights, there is no significant difference, compared to other xenon bulbs. This set uses four ballasts to work, 2 for each side. 4. The Telescopic HID kitIn the US market, BMWs equipped with bi-xenon headlamps also come with adaptive headlamps. Foglights were standard on the 3.0i and 3.0si, and optional on the 2004-2005 2.5i models. The adaptive headlight function itself is the swivel of the headlamps left/right up to 15° based on various sensors and steering input.

Adaptive headlights with bi-xenon bulbs (optional in 2002 models and later) use mirrors and shutters to actively aim the headlights, directing low beams in the same direction as high beams. Headlight assembly seals can wear out over time resulting in water leaks and repeat bulb failures. This article will show you how to remove your E46 headlights.
