Abstract
Official abstract text for this publication.
A vehicle lighting device includes first and second light sources and a light guide lens that is elongate and extending along a direction oblique to a front-back direction of a vehicle. The first light source faces with a back end portion of the lens in a longitudinal direction of the lens. The second light source is arranged close to a front end portion of the lens in the longitudinal direction to emit light toward a back surface of the lens. The lens has a plurality of cut portions in the back surface. The cut portions are arranged parallel with each other in the longitudinal direction, internally reflect the light emitted from the first light source and enters the lens through the back end portion to a forward direction of the vehicle, and refract the light emitted from the second light source and enters the lens to the forward direction.
