ABSTRACT:
To improve visibility by expanding a light emitting range without increasing a size of a light source, in a lighting unit for a vehicle using a projector lamp. A front light has a projector lamp arranged behind an outer lens. A light guiding body is provided from a side surface of the projector lamp to the front. A front surface of the light guiding body emits light along a bottom surface of the front light. A first reflector and a second reflector constituting an isolated extension section extending upwards are arranged opposite to each other holding a distance between them, at a side surface of the projector lamp. The periphery of the first reflector extends out slightly more than the second reflector to form a fringe light emitting section. This causes emission of light of the light guide path in a fringe shape.
