Abstract
A vehicle includes a front end assembly including a headlamp assembly. The headlamp assembly includes a housing that defines a cavity and an outer lens that closes the cavity. A low beam headlamp assembly is located within the cavity. A shared cover lens is located within the cavity. The shared cover lens has an illumination region. A first light guide device directs a beam of light at the illumination region. A second light guide device directs a beam of light at an area offset from the illumination region and also at the illumination region.
Claims20
A vehicle comprising:
- a front end assembly comprising a headlamp assembly, the headlamp assembly comprising:
- a housing that defines a cavity;
- an outer lens that closes the cavity;
- a low beam headlamp assembly located within the cavity;
- a shared cover lens located within the cavity, the shared cover lens having an illumination region;
- a first light guide device that directs a beam of light through the illumination region and toward the outer lens during a first lighting function;
- and
- a second light guide device that directs a beam of light at an area offset from the shared cover lens and also through the illumination region and toward the outer lens during a second lighting function that is different from the first lighting function.
A headlamp assembly comprising:
