An illumination device includes a housing, having an opening, a substrate, a light source, and a light guide. The opening extends through the housing from a first side to a second side of the housing, and includes a first space and a second space. The light guide is disposed across the first space and the second space. The housing has a wall surface that faces the second space and contacts the light guide, a guide rib that extends in a second direction, and a fitting wall that extends in a third direction. The light guide has a first contact surface that contacts the wall surface so as to position the light guide in a first direction, and a guide groove that is fitted to the guide rib so as to position the light guide in the third direction while guiding movement of the light guide in the second direction.

Compact, multi-function rotational controllers or switches that allow an operator of a vehicle to simultaneously view the status of a plurality of related functions, and to easily change or toggle the status of each of the functions. A multi-function controller of the present disclosure may include a rotatable central control dial that is at least partially surrounded by a visual indicator panel that indicates a current status for the functions that are controlled by the multi-function controller. The multi-function controller may include a selected function indicator that indicates which of the plurality of related functions is currently selected, control input hardware that receives operator input, and control circuitry that toggles the state of the selected function responsive to such operator input. The multi-function controller may include an “all functions off” function that allows the operator to simultaneously turn all of the related functions off via a single input action.

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.

A multi-function vehicle lamp having a plurality of light emitting diodes includes a turn input and a tail input with a switch configured to stop current flowing through the tail input when the turn input is energized to increase current flow through the turn input to satisfy minimum current draw requirements of a vehicle current meter that detects turn indicator failure. The lamp may include a single combined turn/stop input, or may include separate turn and stop inputs. Lamps having separate turn and stop inputs block current flow through the stop input when the turn input is energized.

A lighting device is provided for controlling the photometric distribution of light emitted by two or more LEDs. The lighting device may be integrated with a control system of the vehicle and may be controlled by a remote controller. The lighting device may be capable of being operated in one or more modes of operation based on operating conditions, user input, or both. Operating conditions may include vehicle conditions, environmental conditions, and user conditions. The controller may operate a software application to enable the user to modify, control, or otherwise regulate any mode of operation or other feature of the lighting system.

An automotive lighting control system is provided. A light-emitting diode (LED) system of an at least partially autonomous vehicle can include a first group of LEDs including cyan and amber LEDs, a second group of LEDs including cyan and at least one of red or amber LEDs, a third group of LEDs including cyan LEDs, and a controller configured to receive a first control signal indicating whether the at least partially autonomous vehicle is in autonomous drive mode or manual drive mode and cause the cyan LEDs of the first, second, and third groups LEDs to provide perceived cyan light when and only when the autonomous vehicle is in the autonomous drive mode.

A controller for a warning light is disclosed. The controller is composed of a housing, a light emitting element and a control unit. The control unit is in operable communication with the light emitting element of the controller and a light emitting element of a warning light. The controller instructs the light emitting element of the warning light and the light emitting element of the controller to display light in the same lighting mode, which allows vehicle operators to immediately know the lighting mode of the warning light by viewing the lighting mode of the controller.

A U-turn indication system having a signal light retained in a housing integrally formed within a motor vehicle having a plurality of arrows positioned in a radiused orientation to alert surrounding drivers or pedestrians of a U-Turn procedure with a series of lights. This U-turn indication system is mechanically actuated by a switch located inside the interior of the motor vehicle while the signal indicator is located on at least one exterior surface of the motor vehicle. The U-turn indicator having light emitting units is positioned within a light housing of the motor vehicle and is configured to be visually located by pedestrians, drivers of oncoming vehicles, and/or drivers of approaching vehicles.

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.
