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.

The present invention discloses a self-balancing scooter, including a scooter body, wheels, a driving motor, a power supply, a circuit board, a controller and a light emitting lamp. The controller is electrically connected to the circuit board, the power supply and the driving motor. The scooter body includes: an upper shell, pedals, a middle shell, a lower shell and a lampshade. The middle shell is located between the upper shell and the lower shell. The lampshade is provided with at least two spaced lamp strips for transmitting light. The upper shell is provided with lamp holes for placing one or at least two lamp strips. The lower shell is provided with lamp holes for placing one or at least two lamp strips. The sum of the lamp holes of the upper shell and the lamp holes of the lower shell is identical with the quantity of the lamp strips.

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.

A lamp control device comprises a first input terminal, a second input terminal, an output terminal that is configured to be connectable to a lamp via an external switch and outputs a drive current for the lamp, an internal switch provided on a first path connecting the first input terminal and the output terminal, a constant current section provided on a second path connecting the second input terminal and the output terminal, a voltage monitoring section that monitors a voltage applied to the output terminal, and a control section that controls the internal switch on the basis of a monitoring result from the voltage monitoring section.

An automatic light signaling bicycle communication system includes a wireless relay module, a light module, and an external master device. The wireless relay module includes a relay processing unit and a relay communication unit. The relay processing unit controls the relay communication unit to wirelessly communicate with the external master device according to a simplified network protocol. When the relay processing unit receives a brake command through the relay communication unit according to the simplified network layer protocol file, the relay processing unit generates a relay brake command and broadcasts the relay brake command to a light communication unit of the light module according to MAC protocol, allowing a light processing unit of the light module to light up a brake light automatically. The light module only requires a low cost RF receiver chip for receiving broadcasted commands, rather than requiring an expensive chip for handling network communications.

A safety handle designed to be fitted onto a tubular element of an item of mobile equipment, comprises at least one signaling means. The handle further comprises a radio frequency communication module and an electronic circuit for controlling the communication module by a signal of a change in direction.

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.

A first lamp unit and a second lamp unit arranged in a given direction are provided, luminous intensity of the second lamp unit in a lamp forward direction is set to be higher than luminous intensity of the first lamp unit in the lamp forward direction, and the first lamp unit and the second lamp unit are turned on sequentially with time difference. Thus, since the first lamp unit and the second lamp unit having different luminous intensity and being arranged in the given direction are turned on sequentially with time difference, it is visually recognized that emitted light flows from one side to the other, and the light is emitted from both the first lamp unit and the second lamp unit that has higher luminous intensity than that of the first lamp unit. Thus, it is possible to ensure high conspicuity in addition to improvement of functionality.
