The invention relates to an incandescent lamp for a motor vehicle headlight. The secondary filament (2) is arranged in such a way that, in a projection plane that is arranged perpendicular to the reference plane (B), the edge (2a), facing the antidazzle device (4), of the image, projected onto the projection plane, of the second incandescent filament (2) is arranged over the entire length of the second incandescent filament (2) between the reference axis (A) and the antidazzle device (4), and the edge (2a), facing the antidazzle device (4), of the image, projected to the scale 1:1 onto the projection plane, of the second incandescent filament (2) has a prescribed spacing from the reference axis (A). It is thereby possible to produce the light/dark boundary for the lower beam with the aid of the edge (2a) of the secondary filament image (2).
An incandescent lamp for motor vehicle headlights, the incandescent lamp having the following features:
