Abstract: A vehicle lamp includes a light guide including: a first end surface; a second end surface opposite to the first end surface; a front side surface; and a back side surface opposite to the front side surface; a light source disposed to face the first end surface of the light guide so as to emit light toward the first end surface; and a reflector disposed to face the back side surface of the light guide. The light is incident on the first end surface and travels toward the second end surface along an longitudinal direction of the light guide. A first beam of the light is output from the front side surface of the light guide. A second beam of the light is output from the back side surface, and reflected by the reflector to travel toward a forward area of the vehicle lamp.

Abstract: A vehicular lamp including, within a lamp chamber s defined by a lamp body 10 and an outer cover 20, an led 28 which is the light source, and a light guide 24 which guides light emitted from the led 28 by internal reflection so as to emit light at a plurality of locations. the light guide 24 is constructed of a coupling unit u1 that extends along the outer cover 20 and is made of a plurality of light guiding members 25, the surface of each light guiding member 25 formed in an elliptical surface 25a that has a pair of focal points f, are coupled in series while sharing the focal points with each other at coupling portions 26, and the focal points f at both end portions of the light guide 24 (coupling unit u1) are near the light-emitting portion 29 of the led 28.
