A communication system for a vehicle comprises a mechanism for sensing a change in speed of the vehicle and a control device for sending a signal to a headlight activation circuit to modulate the vehicle's headlights based upon the change in speed. In particular, a headlight of the vehicle is able to be modulated as the vehicle reduces speed and/or is decelerating as it approaches an intersection. Additionally, the headlight of the vehicle is able to be modulated as the vehicle accelerates from a stopped position or reaches a certain traveling speed. The headlight activation circuit is able to modulate the headlight between an on position and an off position or modulate the headlight between a high beam position and a low beam position. Consequently, the vehicle is better seen as it approaches likely congestion areas such as intersections and slowing or stopped traffic and attempts to enter traffic.

A headlight module includes a light source, a light guide element, and a projection optical element. The light source emits light. The light guide element has a reflecting surface for reflecting light emitted from the light source and an emitting surface for emitting light reflected by the reflecting surface. The projection optical element projects light emitted from the emitting surface. In a direction of an optical axis of the projection optical element, an end portion on the emitting surface side of the reflecting surface includes a point located at a focal position of the projection optical element.

The purpose of the present invention is to provide a straddle-type vehicle that enables reducing the number of components. Between front forks at the bottom edge of a top bridge configuring a motorcycle, a stay is provided which supports turn signals on each of the front forks. In this case, the stay is configured from a single member. Further, a stay fixing unit for fixing the stay and a first front fork fixing unit for fixing the front forks are provided on the top bridge. By this means, it is possible for the stay to be a single common member that supports turn signals on each of the front forks.

A device 1 for a bicycle, the device comprising: an elongate member 2, the elongate member 2 having a first end 2a arranged to be connected to the handlebar of the bicycle and a second end 2b arranged to extend freely; at least one light source 6 arranged to illuminate at least a part of the elongate member 2; wherein the elongate member 2 is flexibly resilient such that, if a force causes the elongate member 2 to move from a first configuration to a second configuration, the elongate member 2 will return to the first configuration once the force is removed; wherein the elongate member 2 is of a length so as to extend outwardly beyond an end of the handlebar.

A headlight is provided with a light source unit, an aiming mechanism which can adjust aiming with respect to the light source, a headlight cover which is arranged in front of the light source, and a housing which, by fitting with the headlight cover, covers the light source unit and the aiming mechanism. Inside of the headlight, and between the headlight cover and the light source unit, a stay is provided for arranging the light source unit and the aiming mechanism on the headlight cover.

A light sensing illumination device for bicycle includes a seat, a reflector, and an illumination device. The seat includes a housing space. The reflector is disposed in the seat and in the housing space, and the reflector includes a reflection curved face which is formed in a smooth arc shape with a concave face thereof facing an opening of the housing space. The illumination unit is disposed in the housing space and projects light beam toward the reflection curved face. With a smooth arc shaped reflection curved face, the light beam projected by the illumination unit is completely reflected, so as to improve the light condensing effect and efficiently enhance the overall brightness.

A bicycle includes a handlebar, a handle stem on which the handlebar is disposed, a clamp that is attached to the handle stem to fix the handlebar on the handle stem, and a support extending forward and including a first attachment. The first attachment is located farther forward than the handlebar. A display is attached to the first attachment so that the display is placed at an appropriate height to improve visibility of the display.

A communication system for a vehicle comprises a mechanism for sensing a braking of the vehicle and a control device for sending a signal to a headlight activation circuit to modulate the vehicle's headlights based upon the braking of the vehicle. In particular, a headlight of the vehicle is able to be modulated based upon an application of one or both of a front brake and a rear brake. The headlight activation circuit is able to modulate the headlight between an on position and an off position or modulate the headlight between a high beam position and a low beam position. Consequently, the vehicle is better seen as it approaches likely congestion areas such as intersections and slowing or stopped traffic and attempts to enter traffic.

The compact lamp consists of a light source, a focusing lens, a specially shaped secondary lens with a saddle-shaped output surface, a light transmitting element, a battery holding chamber with an electrical control circuit connected to a button for control of the lamp source via a magnetic contact. Some of these elements are placed inside the lamp housing, mounted on an end of a handlebar or another suitable lighting device, and some other elements, including the battery and the magnetic control circuit, are installed inside the handlebar tube or the housing of the lighting device. The compact optical layout enables a beam, which is sharply limited in the vertical plane and sufficiently wide in the horizontal plane and is suitable for daytime running lamps, night headlamps or position lights. When at least two light sources are used in one lamp, beams of different light dispersion patterns can be electrically toggled.

A bicycle including a handlebar attached to a frame at substantially a midpoint, a first set of light sources disposed to project light in a first forward direction, said first set of light sources including a fixed light source and a motor-controlled light source, disposed to project light in a second forward direction said second set of light sources including a fixed light source and a motor-controlled light source, a controller, said controller disposed on the handlebar, said controller coupled to the first set of light sources and the second set of light sources, a rotation sensor operable to sense movement of the handlebar relative to the frame, said rotation sensor coupled to the controller, wherein the motor-controlled light sources move in response to the position of the rotation sensor.
