A light reflective cover includes a concave main reflective surface and a ridge having a connecting surface, a ridge-top reflective surface, a light source end, and a light emitting end. The light source end and the light emitting end are opposite to each other. The connecting surface is opposite to the ridge-top reflective surface and connected to the main reflective surface. The ridge-top reflective surface extends between the light source end and the light emitting end. The ridge-top reflective surface includes a step for dividing the ridge-top reflective surface into a first part near the light source end and a second part near the light emitting end. The second part recesses with respect to the first part toward the connecting surface. The endpoint of the second part at the light emitting end does not protrude beyond an extension line along a first arc formed by the first part.

The active lighting device of a bicycle includes a first optical system with a first light source for long-distance illumination, controlled by a control unit, and a second optical system with a second light source for short-distance illumination, controlled by the control unit. It includes a light sensor for determining the light intensity of a location in which the bicycle is situated 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 determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

An electronic device controls at least one bicycle component in correspondence with operation of an operation device. The electronic device includes a receiver, a memory, a first wireless transmitter, a memory and an electronic controller. The receiver receives operation information corresponding to the operation of the operation device. The memory stores an actuation command of the bicycle component in correspondence with the operation information. The electronic controller receives the operation information and transmits the actuation command corresponding to the received operation information from the first wireless transmitter. The memory is configured to allow the actuation command stored in correspondence with the operation information to be changed.

A vehicle including a light projector, said light projector having a light source disposed to project light through a lens and a removeable imager; a controller coupled to the light projector and operable to receive a user control and direct the light projector to operate the light source; a user control, said user control coupled to the controller, and a rotation sensor coupled to the user control and operable to sense movement of a vehicle steering mechanism, said rotation sensor coupled to the controller, wherein the controller operates the light projector in response to the rotation sensor.

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 handlebar grip set has two turn signals, two operating kits, and two grips. Each of the two turn signals is detachable and has a base, an illumination module assembled to the base, and a housing assembled to the base and covering the illumination module. Each operating kit has a button module electrically connected to the illumination module of a corresponding one of the turn signals. Each one of the grips surrounds the base of a corresponding one of the turn signals. The base of each turn signal is configured to be assembled to one of two ends of a handlebar. The turn signals of the handlebar grip set provide sufficient warning function when a bicycle equipped with the handlebar grip set is turning.
