Abstract
A vehicle lamp assembly includes a first lamp section and a second lamp section, which are disposed inside a lamp chamber defined by a lamp body and a front cover. The first lamp section includes a light source and a reflector which reflects light from the light source. The second lamp section includes a first light emitting device, a second light emitting device, a light guide member, and an optical component. The light guide member includes a base end face from which the light guide member extends in a strip shape along the front cover, a functional portion having a diffusing front surface which emits light from a first light emitting device, and a decorative portion having an internally reflecting rear surface which reflects light from a second light emitting device. A light emitting area of the decorative portion is larger than that of the functional portion. The optical component is disposed on a rear side of the functional portion to guide the light from the first light emitting device toward the diffusing front surface. The light emitted from the second light emitting device is incident on the base end face.
