Abstract
The present invention relates to manufacturing and adjusting the orientation of a motor vehicle headlamp and to a motor vehicle headlamp for performing the method. In a headlamp (7) of the type comprising a transparent front glass (15) fixed to the bodywork (28, 29) of the vehicle and an optical assembly (35, 36) having an optical axis (38) passing through the glass (15), graduated adjustment means (90) are provided for adjusting the orientation of the optical assembly (35, 36) relative to the glass (15) in order to enable the orientation of the optical axis (38) to be adjusted using said means (90) relative to an error as measured between the orientation of the glass (15) as mounted and a predetermined orientation thereof. This makes it possible to use mechanical means for measuring such an error and to adjust the orientation of the optical axis as a result of such measurement providing the headlamp is of the above-described type.
