The invention concerns vehicle headlights with two light functions, comprising a reflector () and a two-filament bulb (), whose first spiral-wound filament (') generates a first light function and whose second spiral-wound filament (&#x2033;) generates a second light function, each light function being associated with a region (&#x2033;) of the reflector (), wherein the second spiral-wound filament (&#x2033;) cooperates with a covering cap () which shields a portion of the light for the light function associated with this spiral-wound filament, which would otherwise impinge on the region (&#x2032;) of the reflector () which is associated with the first light function, wherein the second spiral-wound filament (&#x2033;) generates a turning and/or curve light and the regions (&#x2033;) of the reflector () are separated by a separating line () which extends in a segment of the reflector at an angle of between &#xb1;0 and 35&#xb0;, in particular &#xb1;15 and 35&#xb0;, with respect to the vertical line.

Headlights for vehicles

The low-beam headlight has a reflector, in which a light source is mounted and a light-permeable disk which has optical elements. Light from the light source is reflected as a light beam by the reflector which would illuminate a region (62) of a measuring screen (60) placed in front of the headlight so that the region (62) has a horizontal light-dark boundary without being effected by or without action of the light-permeable disk. A first part of the light beam reflected by the reflector illuminates a first part (64a,64b) of the screen under boundary lines (65a,65b) inclined relative to the light-dark boundary (63). A second part of the light beam reflected by the reflector illuminates a second part (66) of the measuring screen between the light-dark boundary (63) and the boundary lines (65a,65b). A portion of the first part of the light beam is at least partially deflected by the optical elements of the light-permeable disk so that it produces the higher lying section of the light-dark boundary associated with the vehicle's own traffic side of the light beam from the low-beam headlight after passing through the disk.
