A modular portable device (4) for viewing, signaling and/or lighting includes a casing (8) suitable for realizing both a container body and a grip or attachment element of the modular portable device (4). At least one viewing device (12) is suitable to reflect an image of the surrounding environment to the modular portable device (4). At least one signaling device (20) emits a beam of light to signal the presence of the modular portable device and/or the user or vehicle supporting the modular portable device (4). The viewing and signaling devices (12, 20) are mechanically separable from one another and mechanically associable and removable to/from the casing (8) independently of each other.

A wheel of a mobility scooter includes a wheel body provided with a light emitting module. The light emitting module includes an LED lamp bar, a plane mirror and a two-way mirror. The LED lamp bar is disposed between the plane and two-way mirrors. Mirror surfaces of the plane and two-way mirrors face the LED lamp bar therebetween. A perspective surface of the two-way mirror faces an outer side of the wheel. Through optical characteristics of the two-way mirror and the plane mirror, a real image of the LED lamp is reflected back and forth between the two mirrors for infinite times. From the perspective surface, a black hole illusion that LED lamps extend indefinitely into the wheel one after another can be seen, so that the interior of the wheel presents a hollow visual effect which is eye-catching, thereby increasing the product attractiveness and improving the market competitiveness.

A motorcycle includes a pair of left and right front forks, a headlight, cover members (side cowls and light covers), and camera units. A front wheel is rotatably attached to the pair of left and right front forks. The headlight irradiates a forward side. The cover members each having an internal space are disposed at least laterally outside the pair of left and right front forks in a front view. The camera units detect the forward side by acquiring visible light which is one kind of electromagnetic waves (by acquiring images). In a front view, the camera units are disposed below the headlight and laterally outside the pair of left and right front forks. The camera units are disposed in the internal spaces of the cover members.

An active lighting device of a bicycle includes a first optical system with a first light source arrangement for long-distance illumination, which is controlled by a control unit, and a second optical system with a second light source arrangement for short-distance illumination, which is controlled by the control unit. A light sensor determines the light intensity of a location of the bicycle and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a threshold. A speed sensor determines the speed of the bicycle, so that the control unit controls the activation of the light sources of the first light source arrangement from a speed threshold. An orientation or inclination detector selects and adjusts the light intensity of light sources.

A intelligent headlight system for a bicycle according to an embodiment of the present invention comprises: a bicycle body; a portable terminal which may be carried by a rider of the bicycle body and has a GPS module, for detecting the location information of the bicycle body, so as to measure the running speed on the basis of the location information of the bicycle body; and a headlight apparatus which is disposed on the bicycle body so as to cast light on the scene ahead of the bicycle body, is communicatably connected to the portable terminal so as to receive the running speed of the bicycle body, and is formed such that irradiation patterns may vary in accordance with the running speed of the bicycle body.

A notification system notifies brake-related information related to braking of a rotation body of a human-powered vehicle. The notification system includes a notification unit that includes a notification device configured to notify a user of the brake-related information. The notification device is provided on at least one of a brake device braking the rotation body, an operation device operating the brake device, and a display device.

A taillight assembly of a bicycle includes a seat, a seat tube and a clamping element. A bottom of the seat is provided with a seat post. An inside of the seat tube defines an inner space for holding the seat post. A rear of the seat tube defines a wire slot which is disposed for holding a signal wire. The clamping element is fastened to a top of the seat tube. The clamping element includes a taillight fastener, a taillight unit and a wire tunnel. The taillight unit has an indicator surface and an assembling surface. The assembling surface is combined with the taillight fastener. An inside of the clamping element defines the wire tunnel. The wire tunnel is connected to the wire slot. The signal wire passes through the wire tunnel, and then the signal wire enters the wire slot.
