An illumination device for a motor vehicle includes at least one light source and an elongated waveguide which is delimited along the length thereof by a lateral surface. The waveguide is configured to guide light from the at least one light source along a light propagation direction in a totally reflective manner, the light propagation direction corresponding to the length of the waveguide. The light of the at least one light source can be coupled into the waveguide via a coupling surface at an end face of the waveguide, and a decoupling structure is provided in the lateral surface of the waveguide for decoupling light, which exits the waveguide via an exit region of the lateral surface along the light propagation direction, thereby overriding the total reflection condition.

A motor vehicle light device, comprising a light guide layer equipped with optical decoupling zones, and a light generator able to send light toward the light guide layer. The light guide layer is locally covered with a light-absorbing material.

A device for indicating lock status of a motor vehicle door includes a door lock status indicator carried on a window of the motor vehicle door. A device for indicating a turn signal of a motor vehicle includes a turn signal indicator carried on a window of the motor vehicle. These devices may be combined into a single lighting module.

A device for indicating lock status of a motor vehicle door includes a door lock status indicator carried on a window of the motor vehicle door. A window for a motor vehicle includes a luminescent door lock status indicator, a luminescent turn signal indicator and a luminescent blind spot indicator.

Provided is an attachment structure for a lighting device, with which it is possible to reduce the time that attachment requires and stably attach a lighting device to a curved surface on which the lighting device is to be attached without using a screw member. This attachment structure for a lighting device is equipped with: a base provided on a curved surface of a door lining and having a plate-shaped base section; and an attachment part provided on the base and used for affixing the lighting device to the base section.
