1. A vehicular lamp comprising:
a main light source that emits light for forming a predetermined irradiation pattern;
an optical member that allows the light emitted from the main light source to travel toward a front side in an irradiation direction to form the irradiation pattern;
a heat dissipation member that includes a mounting surface on which the main light source is provided, and releases heat from the main light source to outside; and
a light guide member that guides light from an auxiliary light source provided as a separate body from the main light source, wherein
the heat dissipation member includes an opening part that opens the mounting surface, and
the light guide member passes through the opening part and curves toward the main light source, said light guide member further including an emission part that extends in a width direction of the main light source in parallel to the mounting surface.
