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.
