A lamp includes a projection lens, a reflector, and a prismatic lens. The prismatic lens receives direct light, which has been transmitted from the light source outwardly with respect to a widthwise direction of a vehicle, and refracts the received light toward the optical axis. The prismatic lens is separated outwardly from the optical axis in the widthwise direction of a vehicle and is provided between the projection lens and the reflector. The prismatic lens can provide an additional light distribution pattern formed outside, in the widthwise orientation, of a basic light distribution pattern formed from light passed though the projection lens.

Vehicle headlamp

A vehicular headlamp including a discharge bulb which allows mounting of a lighting circuit case to a lamp body using a simple and inexpensive structure and which allows for easy removal of the lighting circuit case therefrom. Because it is disposed within the lamp body, the lighting circuit case need not have a full waterproof structure, and thus it can be formed as a simple, light-weight and inexpensive structure. The lamp body is composed of a main body having an opening and a cover for closing the opening. A mounting portion for the lighting circuit case is formed at a position closely adjacent the opening of the main body of the lamp body. As a result, the lighting circuit case can be easily removed through the opening.

Vehicular headlamp

A vehicle lamp that looks attractive, whether the lamp is on or off, has a transparent cap attached to a reflector having a plurality of reflective surface elements. The transparent cap is attached to the reflector so as to cover the light bulb. A plurality of pillars are provided near the front end portion of the transparent cap for intercepting light emitted from the light bulb. On the front surface of these pillars are formed reflective surfaces. When the lamp is turned off, both the reflective surfaces of the reflector and the pillars glitter. When the lamp is turned on, the spaces between the pillars on the front end portion of the transparent cap shine.
