Horizontal swivelling of the headlights by the stepper motor controller

Horizontal range of movement of headlights

• Inwards, i.e. towards center of vehicle: through a maximum of 7° (for E46, E83, E63)
• Outwards: through a maximum of 15°

This means, for example, that on a right-hand bend:

the right-hand headlight swivels through a maximum of 15° (since the right-hand headlight is on the inside of the bend and therefore swivels outwards away from the vehicle center).

The left-hand headlight swivels through a maximum of 7° (the left-hand headlight swivels towards the vehicle center, i.e. inwards).

The headlight on the outside of the bend reach its end position at the same time as the headlight on the inside of the bend.

On a right-hand bend, the left-hand headlight is on the outside of the bend. The right-hand headlight is on the inside of the bend.
