Abstract: A control device for a vehicular illumination is configured to make definition of factors of an illumination control operation with a higher priority unnecessary when definition of factors of the illumination control operation with the higher priority is the same as definition of factors of an illumination control operation with a lower priority than the illumination control operation with a higher priority.

Abstract: A vehicle is a vehicle that is equipped with an illumination device in a vehicle cabin and that is capable of traveling in an EV mode, the vehicle being configured to change a manner of luminescence of the illumination device when the vehicle enters a low emission zone (LEZ) where the vehicle needs to travel in the EV mode, and to cause a driver to perceive the entrance. For the change in the manner of the luminescence, for example, the color of the luminescence of the illumination device may be changed from a regular color to a specific color. By the change in the manner of the luminescence of the illumination device, it is possible to cause the driver to sensorily recognize the entrance to the low emission zone.
