Reference numeral 1 denotes a tail lamp fixed to a rear part 2 of a bicycle body, and a reflecting concave mirror 3 is disposed on the front surface thereof. The optical fiber 4 for transmitting the light from the headlight is inserted and fixed in the taillight 1 from the rear center of the taillight 1, and the optical fiber 4 has an opening 4 at the end.
a is located at the center of the reflective concave mirror 3.
Reference numeral 5 denotes a hemispherical reflecting mirror disposed so as to face the optical fiber tip opening 4a, and is suspended from the reflecting concave mirror 3 by three supporting rods 6.

The light transmitted from the headlamp is emitted from the front end opening 4a of the optical fiber 4 and travels substantially straight to illuminate the hemispherical reflecting mirror 5, and the reflected light is diffused and hits the entire surface of the reflecting concave mirror, and is further radiated to the front with a large diameter. It The light emitted from the tip opening 4a of the optical fiber 4 is a surface light source having a certain spread (opening angle),
Not only the light parallel to the axis of the optical fiber but also the light is radiated in various directions, so that the light source becomes large, so that the brightness is reduced but the visibility from a distance is improved. A magnifying lens may be attached to the tip opening 4a of the optical fiber 4. The optical fiber may be an optical fiber bundle in which a plurality of optical fibers are bundled.

うことができる。According to the present invention, one end of the optical fiber is inserted from the case side portion of the headlamp arranged in the front of the vehicle body to be positioned in the vicinity of the light source of the headlight, and the other end of the optical fiber is arranged in the rear of the vehicle body. In a taillight device of a vehicle such as a bicycle that is inserted into a taillight that is installed to diffusely emit light transmitted by an optical fiber, a hemispherical reflecting mirror is provided by arranging the opening of the other end of the optical fiber at the center of the reflecting concave mirror of the taillight. Since it is placed opposite the opening of the optical fiber, it is possible to illuminate a large diameter by using an optical fiber with a small diameter, and it is possible to illuminate backwards without using a light bulb as a tail light of the bicycle. The entire lighting system can be performed inexpensively and safely.
