Abstract:
A present invention includes a lamp housing, a lamp lens, a first lamp unit, and a second lamp unit. The first lamp unit includes a semiconductor-type light source, and a light guide member. The light guide member has an exit surface, and a reflection surface. A plane exit surface is provided in a part of the exit surface for blocking a part of a radiated light L4 from the second lamp unit, and a plane incident surface is provided in a part of the reflection surface for blocking a part of the radiated light L4 from the second lamp unit. As a result, the present invention is able to minimize an optical loss of the radiated light L4, even when the light guide member is located at a position for blocking a part of the radiated light L4 from the second lamp unit.
