A method for forming a light engine assembly includes the steps of injecting a light trough material into a mold, thereby forming a light trough including a trough body having an edge, and injecting a seal material into the mold, thereby forming a seal configured to bond with the edge of the trough body. The method further includes cooling one of the light trough material and the seal material to adhere the light trough material to the seal material, thereby forming a unitary light trough part, ejecting the light trough part, and coupling a lighting unit with the light trough part.

The proposed vehicle interior trim part comprises a woven material having at least two parallel optical fibers that are able to laterally emit light and that extend in a longitudinal direction and having at least one further fiber and/or at least one further yarn. The vehicle interior trim part further comprises a reflective layer that is adjacent to the woven material and comprises a fleece material and that is configured to reflect light emitted by the at least two parallel optical fibers. The vehicle interior trim part additionally has a carrier that is adjacent to the reflective layer so that the reflective layer is located between the woven material and the carrier and having at least one light source that is optically connected to at least one of the at least two parallel optical fibers.

A method for visualizing an inclination of a motor vehicle in the motor vehicle, in which the inclination of the motor vehicle is measured and made visible in the interior of the motor vehicle. The inclination is made visible by interior lighting of the motor vehicle. At least one virtual plane is formed, which intersects the motor vehicle horizontally when the latter is in a horizontal position and serves as a reference plane for displaying the inclination. Changes in the inclination of the motor vehicle are modeled dynamically by the interior lighting by the sequential and/or parallel activation of illuminants of the interior lighting.

An illumination apparatus for a vehicle storage cavity is disclosed. The apparatus comprises a circuit disposed proximate to and extending significantly along an opening of the cavity. At least one proximity sensor and a plurality of LEDs suspended in a semiconductor ink are printed on the circuit. The circuit is configured to activate an emission from the LEDs in response to the proximity sensor detecting an object entering the storage cavity.

The disclosure is related to a method and a system for assisting a driver of a road vehicle. A data processing unit receives data representing at least a relative position of the road vehicle, outputs, through a display device and/or an interior lighting device, a visual alert when the data processing unit determines that the data fulfill a first condition, and outputs, through a sound-emitting device, an audible alert when the data processing unit determines that the data fulfill a second condition after fulfilling the first condition.

The vehicle interior component includes a front surface side space and a slit. A light emitting part, which is disposed on a vehicle interior outer side with respect to at least one of the vehicle interior outer side end of the panel lower portion of the upper panel and the vehicle interior outer side end of the panel upper portion of the lower panel and emits light emitted obliquely upward toward an inside of a vehicle interior through the slit, is provided.
