Method of manufacture of a lighting device

A method of manufacture of a lighting device comprising a body of a headlamp or rear light of a motor vehicle that comprises a housing enclosed by a transparent cover, comprising steps, wherein:

• the body of the lighting device is clamped in a fixture and a set of actual positions of control points of the transparent cover or control points of the housing are measured in three coordinate axes;
• the set of measured actual positions of the control points are is compared in a three-dimensional model of the lighting device with a respective calculated tolerance space of control points bounded by permissible deviations from nominal positions of the control points of the lighting device;
• in the event that the set of actual positions of the control points does not match up in all the control points within the calculated tolerance space of control points, a set of corrected positions of the control points with a spatial arrangement which is congruent to the set of actual positions of the control points and which falls by all control points within the required tolerance space of the control points is identified and selected;
• for the chosen set of corrected positions of the control points in the three-dimensional model of the lighting device, determining corresponding corrected positions of the associated locating elements for attachment of the lighting device to a vehicle frame;
• and
• the locating elements are mechanically, thermally, or chemically joined to the housing of the lighting device in the ascertained corrected positions.
