Bi-xenon headlights are also optionally available. Adaptive headlights are currently not planned for the E87.It is not necessary to remove the headlights in order to replace the bulbs. If, for any other reason it is necessary to remove the complete headlight system, the bumper trim panel should be removed to prevent it being damaged.Two headlight adjusting screws are provided (horizontal/vertical adjustment). Adjusting screws are also provided to adjust the gaps between the complete headlight assembly and the body.This function not only enhances the visual appearance of the vehicle but it also serves to minimize wind noise.4 - Front headlight system89Front bumperA new feature of the E87 bumper system is the two-piece design of the bumper trim panel.

If applicable, the PDC sensors and fog lights are accommodated in the trim panel.5 - Front bumper system99Front endAfter removing the bumper trim panel, the complete front end, including the bumper carrier, headlights, air ducts and bonnet lock, can be removed.The bowden cable assembly can be disconnected at its parting point.
