Abstract
A method of manufacturing a lighting device comprising a body of headlamp or rear light of a motor vehicle that comprises a housing enclosing a transparent cover wherein: 1) the body is clamped in a fixture and a set of actual positions of control points of the cover or housing are measured; 2) the measured actual positions of the control points are compared in a three-dimensional model with a respective calculated tolerance space of control points bounded by permissible deviations from nominal positions; 3) if the actual positions of all the control points do not match up within the respective calculated tolerance space of control points, a set of corrected positions is identified and selected; 4) determining corresponding corrected positions of the associated locating elements for attachment of the lighting device from the corrected positions of the control points; and 5) joining the locating elements in the corrected positions.
