A second light device (4b) starts emission of a light pattern B after a first light device (4a) has started emission of a light pattern A. Elements included in the light pattern B and an element included in the light pattern A are arranged on the same straight line.

A system is disclosed for sequentially illuminating segments of vehicle LED arrays of tail lights, when running lights are on, in response to incremental changes in vehicle speed. In response to rapid vehicle deceleration above a predetermined threshold, the system cyclically moves a darkened segment across an illuminated array of LED brake lights with or without the operator applying the brakes.

First lighting bodies are provided to the outer surface of a vehicle body, and second lighting bodies are provided to the outer surface of a trunk lid, which can open/close a trunk. While the trunk lid is closed, a first mode is executed in which the second lighting bodies are lit and the lighting is maintained, and then the first lighting bodies are lit and the lighting is maintained for a prescribed period. When the trunk lid is open, a second mode is executed in which at least the former among the first lighting bodies and the second lighting bodies is lit and the lighting time thereof is set longer than the lighting time of the first lighting bodies in the first mode.

A synchronization signaling system, comprising a set of alert devices comprising at least one of a visual or audio output for producing an alert pattern, a master clock, a timing device capable of receiving updates from the master clock, a controller operably connected with the set of alert devices to control the set of alert devices.

A method and a system for communicating a an ego-vehicle's determined behavior to a target object is for use in a driver assistance system of a vehicle. The method includes steps of acquiring data of a traffic scene preferably by sensor means configured to sense an environment of the vehicle, calculating a prediction result including a target object's behaviour based on the acquired sensor data, determining an action of the host vehicle based on the prediction result and generating an actuation signal for performing the determined action, and determining a communication information indicating the determined action. The communication information is output to a communication means for communication to the target object via at least one of a lighting means of the vehicle and a car-to-x communication means.

An irradiation control device is a device configured to control irradiation of light indicating a predetermined intention to a surrounding person, and includes an irradiation control unit configured to perform control to irradiate a first irradiation element, and a second irradiation element, which is irradiated when the first irradiation element is extinguished, and indicates an intention of the irradiation. As a result, light can be irradiated such that the attention of a target person is easily attracted and a delay in understanding by the target person is easily avoided.

To achieve visibility improvement and reduction of sense of incongruity in a vehicular lamp using LEDs. A lighting control device for controlling the on/off of a light source having a first and a second lamp unit each with LEDs including: a control part that generates a control signal for controlling the emitted lights of the lamp units; and a light source drive part for driving the lamp units based on the control signal; where the light emitted from the two lamp units driven by the light source driving part is such that each luminous intensity decreases from a first value to a second value which is smaller than the first value within a common period, and each luminous intensity decreases to the second value during the common period maintaining the relationship that the luminous intensity of the first lamp unit is lower than that of the second lamp unit.

A vehicle illumination system and method for controlling a vehicle light. The method includes receiving an input signal at a controller port; generating a control signal to activate the vehicle light based on both a rising and falling edge of the input signal in which the control signal activates an animation sequence when a falling edge is detected.

A lighting control system of the type including an electronic device with a processor, memory, wireless communication capability and a user interface may be used. A controller may be used with a receiver to receive wireless communication from the electronic device and an output terminal with at least one lighting array in electrical communication with the output terminal of the controller. A power supply may be provided with the controller thereby providing electrical power to the controller and the lighting array. Software on the electrical device may be used providing a graphical interface with a user to actuate the controller to provide an electrical output to the lighting array. The combination may be placed on a building, vehicle or any object to allow a plurality of lighting themes and palettes. Music may also be used to control the lighting output as well as speed or acceleration.
