A lamp unit has a first light source, a second light source which is illuminated when the first light source is turned off, and a projection lens having a first entering surface which is associated with a first focal point and a second entering surface which is associated with a second focal point. Light emitted from the first light source is incident on the first entering surface and passes through the projection lens. The second light source is disposed between the first light source and the projection lens in a position through which light emitted from the first light source to reach the first entering surface does not pass. Light emitted from the second light source is incident on the second entering surface and passes through the projection lens.
