Abstract: A lamp, which has a light source and a fiber-optic light guide that is led, over part of its length, in the housing of a sewing machine, and whose end piece projects from the housing, is to be arranged on the sewing machine such that a desired machine part can be illuminated without the work area and the field of view of the sewing machine operator being disadvantageously affected by the lamp. To achieve this, the end piece of the fiber-optic light guide is adjusted to the shape of a housing part and is received on the housing part, hidden by the side of the housing part facing away from the housing.
