A lighting and/or signaling device for a motor vehicle. Further, the device includes a light guide having a light incident region, a first optical region, a second optical region, and a third optical region. Further, the first optical region is configured to receive and redirect incident light rays from the light incident region to the second optical region as a first set of light rays. Further, the second optical region is configured to receive the first set of light rays, refract a first portion thereof towards an exit facet and reflect a second portion thereof towards the third optical region as a second set of light rays. Further, the third optical region is configured to receive the second set of light rays and is configured to reflect the second set of light rays towards an exit facet of the third optical region.

A flat light guide (1) for a vehicle lighting device, which includes a rear end (10) and a front end with a light output surface (13), the light guide (1) being defined between the two ends by a pair of side surfaces (11, 12). The light guide (1) has a base plane (X-Y) and at its rear end (10) is provided with at least one collimating element (2) arranged transversely or obliquely with respect to the plane (X-Y). Opposite the collimating element (2) is arranged an obliquely inclined reflective surface (3) to reflect light from the collimating element (2) into the flat light guide (1). The collimating element (2) is adapted for the light input from the light source into the light guide (1) which further guides the light between the side surfaces (11, 12) to the output surface (13).

A vehicle lamp includes: a first light source and a second light source having light emission colors different from each other; and a light guide body that receives and emits light from the first light source and the second light source. The light guide body includes an incident portion on which the light is incident, a reflecting portion that reflects the light incident from the incident portion, and an emitting portion that emits the light reflected by the reflecting portion. The reflecting portion includes a plurality of first light distribution control surfaces that reflects the light from the first light source toward a predetermined direction and a plurality of second light distribution control surfaces that reflects the light from the second light source toward the predetermined direction. The plurality of first and second light distribution control surfaces are alternately arranged.
