A rear hidden lighting system for an automobile is comprised of a lamp mounted to a bracket attached to the vehicle's rear structure, a linear actuator mounted to the vehicle's structure which rotates the lamp, an electronic relay system which powers the linear actuator in two directions, a switch mounted to the transmission of the vehicle which provides switched power to the linear actuator. When the vehicle is placed in reverse gear, the lamp will rotate out of a hidden position becoming visible and lighting the rear of the vehicle. The lamp will rotate back to the hidden position when the vehicle is taken out of reverse gear. An objective and benefit is that the lamp and bracket and the linear actuator can be mounted to existing attachment points on the vehicle which will not necessitate drilling holes, altering vehicle componentry or welding parts to existing vehicle parts or structure.

A projected display with improved visibility and understandability of a vehicle behavior. A vehicle projection device includes a projector that forms a projected image on a road surface; and a control unit. The control unit causes the projector to perform flashing projection of the projected image in a first period from start of projection, and causes the projector to perform sequential projection of the projected image in response to transition from the first period to a second period.

Electronic device comprising an electronic circuit that receives signals from a sensor and which are processed by a microcontroller, such that if an increase or decrease of time is detected between the signals sent by the sensor, they will be interpreted as an acceleration or deceleration respectively, being activated the acceleration or deceleration lighting devices as appropriate.

A management system for a work vehicle, includes: a traveling condition data generation unit configured to generate traveling condition data of a work vehicle having a notification device configured to notify a moving direction; a notification data generation unit configured to generate notification data for controlling the notification device such that, based on the traveling condition data, the notification device operates in a first state at a time of moving forward of the work vehicle, and the notification device operates in a second state different from the first state at a time of moving backward of the work vehicle; and an output unit configured to output the notification data, to the work vehicle.

A vehicle messaging system and method of operation thereof. The method of operating the vehicle messaging system includes first providing a vehicle messaging system. Once provided, a message to be displayed will be inputted into the vehicle messaging system by a vehicle operator and/or one or more users of the vehicle messaging system. After the message to be displayed has been inputted the vehicle operator and/or the one or more users will instruct the vehicle messaging system to display the message.

A light for the exterior of a vehicle includes at least one illuminant and a lens. The illuminant emits light in an activated state that hits the lens directly or indirectly via a reflector. The lens is transparent to light in a first predetermined wavelength range and reflects light in a second different wavelength range when the illuminant is deactivated. The illuminant is at least one light-emitting diode (LED). The diode emits light in a third wavelength range, which is predetermined such that the emitted light, after transmission through the lens, is present in a predetermined fourth wavelength range that is at least different from the second wavelength region. The light can be used as part of a rear light in a vehicle.

An opening and closing body control device is applied to a vehicle that includes a vehicle body having an opening, an opening and closing body configured to open and close the opening, a drive unit configured to operate the opening and closing body, and a detection device configured to detect a gesture operation of a user. The opening and closing body control device includes: a position acquisition unit configured to acquire a position of a portable device carried by the user by wireless communication; an operation determination unit configured to determine whether the gesture operation is executed in a situation where the portable device is present in a detection area of the detection device; and an opening and closing body control unit configured to operate the opening and closing body based on a content of the gesture operation when it is determined that the user executes the gesture operation.

When information regarding a situation inside and outside a vehicle is determined to match a display change condition, a control unit (32) changes a display mode of information displayed outside the vehicle by controlling a projector device (4a) or a body light device (4b).
