Abstract: An in-vehicle illumination system which is to be disposed in a door of a vehicle has: a door warning lamp which is disposed in the vicinity of a door handle that is operated when the door is to be opened, and which indicates an open/close state of the door; a door handle illumination lamp which illuminates the door handle; a decorative lamp which emits decorative light; and a first control connector having a first control apparatus which controls ON/OFF states of the door warning lamp, the door handle illumination lamp, and the decorative lamp. The first control apparatus of the first control connector causes, when the door is in an open state, the door warning lamp, the door handle illumination lamp, and the decorative lamp to be lighted ON with a predetermined warning color.

Abstract: A vehicular illumination mechanism is mountable on a vehicle having a loading and unloading mechanism for moving a wheelchair between the vehicle and a road surface. The loading and unloading mechanism has an upper face portion and is movable between a stored position and an extended position. The vehicular illumination mechanism includes a position detection portion that is configured to detect a position of the loading and unloading mechanism, an illuminating lamp that is configured to illuminate the upper face portion of the loading and unloading mechanism extended to the extended position, and an illumination control portion that is configured to light the illuminating lamp when the position detection portion detects that the loading and unloading mechanism is in the extended position.
