2. Description of the Related Art
Conventional motorcycle headlamps include a headlamp in which an extension is provided in such a manner to cover the front end of a reflector (see Japanese Patent Application Publication No. 2008-84595, for example).
According to Japanese Patent Application Publication No. 2008-84595, an extension is disposed in front of the front end edge of a reflector constituting a headlight.
The extension is formed of an opaque member and a light transmissive member. Light reflected by a parabolic dedicated reflection surface provided on an outer side of the reflector is transmitted through the light transmissive member of the extension. In this way, the extension appears as illuminated or shining.
According to the above technique, when the extension emits light, for example, in an annular shape, the visibility and the appearance of the headlight is improved. However, the technique employs a structure in which the extension emits light by applying reflected light from the parabolic dedicated reflection surface to the extension. Hence, the extension cannot emit light if the extension is disposed, for example, at a position which the reflected light cannot reach. This leads to a restriction on the design freedom of the headlight. Also, it is difficult to form the extension such that its light emitting part would have, for example, a laterally expanded appearance. Specifically, in a case of a left-right two-lamp headlight, the headlight may be stretched laterally. In contrast, in a case of a top-bottom two-lamp headlight, lateral expansion of a light beam and/or an original characteristic design are/is desired. For this reason, it is desirable to devise top-bottom two-lamp headlights.
