How It Works

WARNING: This page does not describe the selected car, but rather 37 other vehicles, including the 2006 BMW 330Ci, 2006 BMW 325Ci, 2005 BMW M3, 2005 BMW 330xi, and 2005 BMW 330i. However, it is still accessible from the selected car via links, so may be relevant.

When the dipped beam headlights are switched on, the mechanical screen is positioned vertically in front of the D2-S bulb (as illustrated). The beam of the xenon headlight is thus dipped.

When the main beam headlights are switched on, the mechanical screen in front of the D2-S bulb is moved from the vertical to the horizontal (folded forwards in the direction of travel).

This redirects the beam of the xenon headlight to main beam headlights. The rays of lights are able to shine uninterrupted to the front and to make use of the complete area of the reflector and the lens.

The mechanical screen in front of the D2-S bulb is controlled by the light switch cluster. If the light switch cluster is not able to actuate the lifting magnet for the mechanical screen, the screen is pulled back to the vertical position by the return spring.
