Adjustment Of Headlight Horizontal Aim

The stepper motor controllers move the headlights to the right or left when the vehicle corners.

Horizontal range of movement of headlights:

• Inwards, i.e. towards centre of vehicle: up to max. 8°

  > E60, E61, E65, E66: 8°

  > E46, E63, E64, E83, E90: 7°)

• Outwards: up to max. 15°

Example: Right-hand bend:

The right-hand headlight turns by up to 15° (the right-hand headlight is the "inside" headlight on a right-hand bend).

Viewed from the vehicle, the right-hand headlight moves "outwards".

The left-hand headlight moves up to 8° (the left-hand headlight moves towards the vehicle centre, i.e. "inwards" as viewed from the vehicle).

The headlight on the outside of the bend reaches its end position at the same time as the headlight on the inside of the bend to ensure that the illumination of the road is smooth and even.

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.
