Abstract
A headlight for a motor vehicle which can selectively be used as an ordinary headlight or a fog light. A yellow cover is slidably mounted slidable along the axial direction of the bulb of the headlight so that it can be moved between a position where is surrounds the bulb, in which light emitted by the bulb must pass through the cover before reaching the reflector, and a position where the light from the bulb can proceed directly to the reflector without passing through the cover.
Claims17
A headlight for a motor vehicle, comprising:
- reflector;
- a bulb positioned adjacent said reflector;
- a yellow cover;
- and
- means for slidably moving said cover parallel to an axial direction of said bulb between a first position surrounding at least a portion of said bulb where light from said bulb passes through said cover before reaching said reflector and a second position where light from said bulb proceeds directly to said reflector without passing through said cover.

A headlight for a motor vehicle, comprising:
- (1) a reflector;
- (2) a bulb positioned adjacent said reflector:
- (3) a yellow cover;
- and
- (4) a mechanism for slidably moving said cover parallel to an axial direction of said bulb between a first position concentrically surrounding at least a portion of said bulb so that light from said bulb passes through said cover before reaching said reflector and a second position where light from said bulb proceeds directly to said reflector without passing through said cover, said mechanism comprising:
- (a) a case mounted within a recess in said reflector, said case having a longitudinally extending guide hole formed therein extending in said axial direction and aligned with a notch in said reflector;
- (b) a guide rail formed on said case extending parallel to and adjacent said guide hole and extending into said notch:
- (c) a drive screw disposed in said case and extending parallel to said guide hole;
- (d) motor means for rotating said drive screw:
- (e) a moving member threadedly engaged with said drive screw and having an engaging portion extending through said guide hole;
- and
- (f) a holder having a pedestal portion supporting said cover a recess being formed in a lower portion of said holder slidably fitted on said guide rail, said engaging portion being engaged with said holder to slide said holder along said guide rail as said drive screw is rotated.
