At least certain rods are electrically interconnected in a first assembly dedicated to an emission of a light beam at a first wavelength, and other rods are electrically interconnected in a second assembly dedicated to an emission of a light beam at a second wavelength different from the first wavelength, the first and the second assemblies forming two selectively activable emission areas.

An agricultural work vehicle for operating in a field includes a chassis, a cab mounted to the chassis, a controller for controlling operation of the work vehicle, and a lighting system including a array field light. The controller is in communication with a field map input, and the array field light projects a light emission to illuminate a zone. A light control module is disposed in electrical communication with the controller and operably controls the array field light. Upon identifying an object in the field based on the field map input, the controller determines if the object is in the zone. If the object is in the zone, the light control module controllably adjusts an output from the array field light based on a location of the object in the zone.

A control system for a turn/brake light of a vehicle, includes a control circuit configured to receive a plurality of analog voltage inputs and to deliver an analog voltage output based at least upon the plurality of inputs. A light emitter is connected to the control circuit. The light emitter includes at least one dual-color LED configured to be selectively illuminated based on the analog voltage output. The control circuit can receive a turn/brake signal and produce at least a first output voltage and a second output voltage.

An improved Center High Mounted Stop Lamp (CHMSL) harvests electrical power while providing additional features when the CHMSL is not powered during a brake application. Electronic circuitry determines if the different sources of electrical power have sufficient energy to activate the light-emitting device; senses a vehicle braking or emergency event to activate the light-emitting device upon sensing the event; and switches from one source of electrical power to a different source of electrical power if it is determined that a particular source of electrical power has become depleted or incapable of activating the light-emitting device. The different sources of electrical power may include a supercapacitor, a rechargeable battery, or a primary battery. The electronic circuitry operative to sense a braking or emergency event may include a brake signal input or an inertial measurement unit (IMU).

A lamp for a vehicle or other object that includes multiple functions. In one aspect, the lamp includes a first circuit for emitting a first color light (such as red light), and at least a second circuit for emitting a second color of light (such as amber light). In another aspect, the lamp optionally includes a microcontroller that may be programmed to control the activation of the different colored lamp circuits based on lamp location information, and based on an operating mode.

An illuminated communication unit for a vehicle is provided. The communication unit may include an enclosure carrying components within a cavity that include a printed circuit board assembly (PCBA) and a heat sink. The PCBA may include a position sensor in communication with the vehicle and configured to detect a position of the vehicle, and a plurality of light emitting elements disposed adjacent to the position sensor and configured to generate a light output.

Examples provide a vehicle multicolor light control system for managing light devices using serial data communication. A vehicle includes a plurality of multicolor light devices and a plurality of physical light control switches. A light controller device acts as an intermediary device between the light devices and the switch devices. The light controller device sends a data packet including instructions for controlling light activation, light deactivation, color combinations of the light, flash pattern of the light device and other functions of the light device in response to user activation or deactivation of one or more of the physical switch devices, a vehicle function activation, input from a user interface device or other data indicating a user-selected mode. The instructions in the data packet can control a single light device or multiple light devices within the same light device zone.
