A method for producing motor vehicle lamps, which each comprise: - a lamp interior enclosed by a lens and a lamp housing and accommodating at least one lighting means with at least one light source, - a lamp housing with at least one light opening for light emission, which light opening is shut off by the lens and enclosed by at least one wall of the lamp housing in the finished motor vehicle lamp, wherein: - the wall has an inner surface facing toward the light opening and an outer surface averted from the light opening and also a circumferential rim surface around the light opening, which rim surface adjoins the inner surface along an inner edge reflecting the surface profile of the light opening with its outline and adjoins the outer surface along an outer edge, and which rim surface connects the inner surface to the outer surface between the inner edge and the outer edge and continues the surface profile of the light opening, and - at least one reception point is provided at the lamp housing, characterised by the process steps: - equipping the lamp housing with the fittings and components accommodated in the lamp interior of the finished motor vehicle lamp, - producing a lens formed according to the surface profile of the light opening with the lens being oversized such that it projects beyond the outer edge of the rim surface in at least one direction when placed onto the rim surface, - shutting off the light opening by placing the lens onto the rim surface and connecting the lens to the lamp housing, wherein the lens projects beyond the outer edge in the at least one direction, - inserting the motor vehicle lamp accurately positioned into a reception, according to the arrangement of said motor vehicle lamp in an installation opening, - cutting (VIII) the portion of the lens projecting beyond the outer edge by taking the reception points as reference points, and - extracting the motor vehicle lamp from the reception. - a lamp interior enclosed by a lens and a lamp housing and accommodating at least one lighting means with at least one light source, - a lamp housing with at least one light opening for light emission, which light opening is shut off by the lens and enclosed by at least one wall of the lamp housing in the finished motor vehicle lamp, - the wall has an inner surface facing toward the light opening and an outer surface averted from the light opening and also a circumferential rim surface around the light opening, which rim surface adjoins the inner surface along an inner edge reflecting the surface profile of the light opening with its outline and adjoins the outer surface along an outer edge, and which rim surface connects the inner surface to the outer surface between the inner edge and the outer edge and continues the surface profile of the light opening, and - at least one reception point is provided at the lamp housing, - equipping the lamp housing with the fittings and components accommodated in the lamp interior of the finished motor vehicle lamp, - producing a lens formed according to the surface profile of the light opening with the lens being oversized such that it projects beyond the outer edge of the rim surface in at least one direction when placed onto the rim surface, - shutting off the light opening by placing the lens onto the rim surface and connecting the lens to the lamp housing, wherein the lens projects beyond the outer edge in the at least one direction, - inserting the motor vehicle lamp accurately positioned into a reception, according to the arrangement of said motor vehicle lamp in an installation opening, - cutting (VIII) the portion of the lens projecting beyond the outer edge by taking the reception points as reference points, and - extracting the motor vehicle lamp from the reception.
