Abstract:
A vehicle lamp includes a light guide extending in a first direction intersecting a front-rear direction of the lamp, a light source arranged to input light into the light guide from an end face of the light guide, and a reflector arranged behind the light guide to extend in the first direction. Reflecting elements on a rear surface portion of the light guide internally reflect the light toward a front surface portion of the light guide. The reflector has a first reflecting portion disposed behind the reflecting elements and a second reflecting portion disposed adjacent to the first reflecting portion in a second direction intersecting the first direction. The first reflecting portion reflects a portion of the light that has leaked rearward from the reflecting elements, and the second reflecting portion forwardly reflects the portion of the light that has been reflected by the first reflecting portion.
