A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, and a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output through the interface to the vehicle wiring harness that causes a strobing of existing vehicle hazard lamps.

The light source of the present disclosure spot-irradiates a distant place in front of a vehicle. The turn on/off circuit supplies a driving current I.sub.LD to the light source 120 to turn on the light source. The swivel mechanism swivels the light source. The turn on/off circuit reduces a light quantity of the light source as a swivel angle θ of the swivel mechanism is large.

Device for controlling at least a first light source of a motor vehicle, the motor vehicle at least comprising the first light source being configured to provide a first light function and a second light source configured to provide a second light function, the device comprising: electrical means configured to detect activation of the second light source, and to deactivate the first light source after detection of activation of the second light source. Also, method for controlling at least a first light source of a motor vehicle, the motor vehicle comprising the first light source being configured to provide a first light function and a second light source configured to provide a second light function, the method comprising: electrically detecting activation of the second light source; and electrically deactivating the first light source after detecting activation of the second light source.

In a vehicle front lighting apparatus, the number of switch elements brought into an opened state and an applied voltage value is detected every time a predetermined detection condition is satisfied, the amount of change from the number of switch elements detected last time and the amount of change from the voltage value detected last time are acquired, and it is determined that a disconnection has occurred if the amount of change in the number of switch elements does not match the amount of change in the voltage value.

A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

A present invention provide a vehicle light system which prevents low-beam headlights from being forgotten to turn on while a vehicle is traveling and is able to turn off the low-beam headlights when it is not necessary, a rotation position of a light switch includes an AUTO position, a SMALL position, and an OFF position, the light switch includes a momentary mechanism which returns a position to the AUTO position when the position is changed to the OFF position or the SMALL position, lights include the low-beam headlights and position lights, the AUTO position allows the low-beam headlights and the position lights to turn on or off depending on a brightness outside the vehicle, and a light control unit turns off the low-beam headlights and turns on the position lights when the rotation position is set to the AUTO position, the brightness outside the vehicle is lower than a predetermined value, a speed is lower than a first predetermined speed, and the rotation position is then changed to the SMALL position or the OFF position.

A vehicle headlight system has at least one headlight having low, high and off modes. A controller is electrically connected to the at least one headlight and communicates with a switch. The switch has first, second and third positions. The second position is intermediate the first and third positions, and is biased to return to the second position from the third position. The controller controls the at least one headlight to be: in one of the low beam mode and the high beam mode when the switch is in the first position; in another one of the low beam mode and the high beam mode when the switch is in the second position; in the off mode when the switch is in the third position for more than a predetermined amount of time. A method for controlling at least one headlight of a vehicle is also disclosed.

A motor vehicle horn and light system accommodating sounding a vehicle horn and illuminating one or more vehicle exterior lights when a user-operated button is pressed. The electrical circuit includes a battery electrically connected to a horn and light system computer. The system computer includes a processor and an input/output interface. The system circuit further includes a user-operated button electrically connected to the battery, to a vehicle horn, and to an input port of the system computer. The system computer is electrically connected to a light relay module via an output port, and the light relay module is connected to a vehicle exterior light. The system computer processor can be programmed to illuminate or flash the exterior light as desired. The system may further include a horn and light system switch and may also include a vehicle main computer electrically connected to the light relay module.
