A light-transmitting member is arranged such that light emitted from a light guide enters. Light which enters an incident end surface is emitted from an emitting end surface. The light-transmitting member has a wide width portion and a narrow width portion. A width of the incident end surface of the wide width portion is larger than a width of the light guide in a direction perpendicular to a longitudinal direction of the light guide. A width of the incident end surface of the narrow width portion is smaller than the width of the incident end surface of the wide width portion. The incident end surface has a curved surface convex toward the light guide at least in the wide width portion. A curvature of the incident end surface in the wide width portion is greater than a curvature of the incident end surface in the narrow width portion.

A light guide (1) for a motor vehicle, wherein the light guide (1) has a light-guiding body (10) made of transparent plastics material, wherein the light-guiding body (10) has at least one light-entrance surface (11) and at least one light-exit surface (12) and wherein the light-guiding body (10) is covered in a region by means of a substantially light-opaque cover material (20), wherein the cover material (20) is applied onto the region by means of an injection molding method. The use of such a light guide (1) in a motor vehicle and a method for producing such a light guide (1).

A lamp for automotive front lighting and a vehicle headlight comprising the lamp are described, as well as a method of manufacturing the lamp. The lamp 10 comprises a base 12 for mechanical and electrical connection to an automotive headlight 50. A burner 14 is fixed to the base 12 and comprises a sealed transparent vessel 22. A first filament 34 is arranged within the vessel 22. A holding wire 30c is arranged within the vessel, and a baffle 40 is arranged proximate to the first filament 34 to partially shield light emitted from the first filament 34. The baffle 40 is fixed to the holding wire 30c. The transparent vessel 22 comprises a vessel wall including a cylindrical portion 24 surrounding the first filament 34. In order to obtain a lamp which may withstand vibration, a support member 38, 138, 238 is provided including at least a first part 39 fixed to the baffle 40 or to the holding wire 30c and a second part 43 which is in contact with the cylindrical portion of the vessel 22. The support member 38, 138, 238 comprises a flexible intermediate part 37 connecting the first and second parts, such that the baffle 40 or the holding wire 30c is supported resiliently against the vessel 22.

An accent lamp (10) having a solid state light source (4), such as LEDs, is attachable to a rear surface of an automotive headlamp (40) opposite the light-generating capsule (44). Accent lamp (10) has first retaining member (20), such as a clamp, formed above printed circuit board (8) on which LED (4) is mounted. Headlamp base (60) defines light passageway (45), formed as a light guide (42), extending from outermost peripheral surface (63) to an upper surface (61) on which lamp capsule (44) is retained. Accent lamp (10) is readily detachably mounted to headlamp (40), preferably by resilient first and second retaining members (20, 24), and, when mounted, can be biased to promote optical coupling of light source (4) to light guide (42).
