This vehicle lamp fitting (10) includes a plurality of arranged light sources (12) and a light guide body (11) into which light from the plurality of light sources (12) is introduced. The light guide body (11) includes a light entry section (15) into which the light from the plurality of light sources (12) is incident; a light exit surface (11a) extending in an arrangement direction of the plurality of light sources (12); a step-shaped first lens cut section (21) provided between the light entry section (15) and the light exit surface (11a) and extending in the arrangement direction; and a step-shaped second lens cut section (22) provided between the first lens cut section (21) and the light exit surface (11a) and extending in the arrangement direction.

A high mount stop lamp mounted on a rear portion of a roof of an automobile is provided. The high mount stop lamp includes a flat light guide arranged below a resin roof panel. The light guide includes a front end and a rear end. The high mount stop lamp also includes a light source opposing the front end of the light guide. The rear end of the light guide is located on or proximate to a rear end of the roof panel to function as a light emitting portion.

An automobile headlamp comprising a light source; a photochromic lens; and a one-way mirror positioned between the light source and the photochromic lens such that when viewing the light source through the photochromic lens, the one-way mirror conceals at least a portion of the light source.

A lamp device for vehicle 1 comprises a light source 2, an inner lens 3 configured to accept light of the light source 2, and a housing 5 configured to cover a periphery of the light source unit 2 and the inner lens 3. When a traveling direction of a light beam with a largest light amount in the light emitted from the light source 2 is defined as front, the housing 5 includes a back surface portion 51 located on a rear side of the inner lens 3, and a lower surface portion 53 located on a lower side of the inner lens 3, the lower surface portion 53 includes an extended portion 53a extended to a front side of a front surface portion 31a of the inner lens 3.

A first light source illuminates a first region. A second light source is configured to provide lower luminance than that of the first light source. The second light source illuminates a second region that overlaps the first region, and that has a larger area than that of the first region. A lighting circuit drives the first light source and the second light source according to a common lighting instruction. The lighting circuit gradually turns on the first light source and the second light source with different gradual changing time periods in response to the lighting instruction.

In a light source for headlight, the light emitting element is arranged to be displaced from an optical axis of the projection lens part. The reflection surface part is in a shape of a concave mirror having an optical axis and one focal point on the optical axis. An optical center which is an intersection of the reflection surface part and the optical axis of the reflection surface part is arranged on the optical axis of the projection lens part and between the projection lens part and a focal point of the projection lens part. The optical axis of the reflection surface part is oriented in a direction passing a position between a central part of a light emitting surface of the light emitting element and a central part of the projection lens part.

Disclosed is a case structure for a rear combination lamp in an automobile in which a rear combination lamp case in a corner portion formed in a rear portion of a vehicle is formed in a corner case having a substantial triangle pyramid shape by a rear plate, a side plate and a planner plate, wherein the rear plate forms a case rear face on which a concave notch portion is formed in a substantial center, wherein the side plate forms an air communication side face which is formed so as to gradually become narrower width toward a rear thereof, and wherein the planner plate forms a concave air communication path in a center thereof so that a terminal end of the concave air communication path communicates with the concave notch portion of the rear plate.
