A seatpost has a post body, an adjusting mount, a connecting unit, and a connecting bracket. The post body has a supporting base disposed at an upper end of the post body. The supporting base has a bore formed through a rear end of the supporting base. The adjusting mount is connected to the supporting base and has a passing hole disposed at a rear end of the adjusting mount. The connecting unit is connected to the adjusting mount and has a connecting portion having a threaded hole. A bolt passes through the bore, the passing hole, and is screwed with the threaded hole. The connecting bracket has a front end connected to the connecting portion, a rear end opposite the front end, and an assembling board disposed at the rear end of the connecting bracket for assembling a taillight or a bicycle license plate.

A lighting device includes an LED, a light guiding member, and a mask member. The light guiding member has a cut to provide a directivity to light emitted from the LED. The cut is provided at a position corresponding to the LED on an emission surface side of the light guiding member. The mask member is disposed on an emission surface side of the cut to block the light emitted from the LED.

A motorcycle (1) includes a tail lamp (41), a rear covering (32), rear end components which are a license plate (44) and a license lamp (46), a rear stay (33), and a sensor (60). The tail lamp (41) emits light toward the rear side. The rear covering (32) is provided with the tail lamp (41). The rear end components are disposed more rearward than the rear covering (32). The rear stay (33) extends at least rearward from a connecting portion connected to the rear covering (32), and supports the rear end components. The sensor (60) for sensing an object rearward is at least partially received in an internal space (111) that is formed either in the rear covering (32) or in the rear stay (33).
