The headlamp has a lens (L) provided in front of an axial filament lamp (10) so that the headlamp provides a cut light beam. The headlamp does not have a reflector. The lens is arranged such that extreme incident light rays emitted by the lamp are refracted in output of the lens, parallel to an optical axis (Y). Other incident light rays emitted by the lamp are refracted with an inclination towards the bottom with respect to the axis. A mechanism is provided for adjusting the site angle of an optical module and allows to adjust the cut light beam with respect to the horizontal. |
