The present invention refers to a method and a device for sequentially operating light source, in particular a lighting system for signalizing a change of driving direction of a motor vehicle, comprising a plurality of light emitting diodes (LED) connected in series, said diodes can be activated in a pre-determined sequence within a required time frame t.sub.0. The method comprises activating within a required time frame (t.sub.0) a sequential operation of a plurality of LEDs, wherein the operation of the first LED in the plurality of LEDs and operation of the last LED in the plurality of LEDs is carried out within an actual time frame (t.sub.1) of operation. The method further comprises activating after lapse of a safety time frame (t.sub.2) of all LEDs (1.sub.1, 1.sub.2 . . . 1.sub.n) simultaneously.

Provided is to a vehicle lamp capable of ensuring a high sense of unity when a plurality of lamp units are arranged based on a shape of an outer optical member. The vehicle lamp includes a light source unit for generating light, a first optical member in which a plurality of incident optics are disposed on an incident surface, a second optical member in which a plurality of emitting optics are disposed, and a shield unit disposed between the plurality of incident optics and the plurality of emitting optics.

A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.

A vehicle light assembly, a system, and a method for reducing electromagnetic interference are provided. The vehicle light assembly includes a light source, DC-DC conversion circuitry including a switch, and a microcontroller. The microcontroller is configured to generate a reference voltage, the reference voltage being changed periodically within a predetermined range, and drive the switch associated with the DC-DC conversion circuitry with a signal based on at least the reference voltage.

A method for controlling one or more vehicle lights of a vehicle during execution of a vehicle function based on image analysis is provided. The method includes receiving instructions to analyze one or more images captured by a camera supported by the vehicle. The method also includes transmitting instructions to a vehicle light system including the one or more lights positioned within a vicinity of the camera. The instructions causing a change in a current state of the one or more lights to a temporary state. During the temporary state, the method includes receiving one or more images from the camera, and identifying one or more reference points within the one or more images.
