Abstract

The invention relates to a lamp for motor vehicles that at least comprises a first incandescent filament that is intended to produce a light beam having a light/dark cutoff line, the incandescent filament having associated with it for this purpose a shielding cap to restrict the light emitted to a given angular range. The shielding cap (4) has at least one opening that is intended to produce a light beam above the light/dark cutoff line, with at least part of this light beam, which light beam passes through the said opening, not passing through and/or passing through a color filter.
