Vehicle exterior lighting systems for vehicles equipped with tailgate assemblies may be configured to provide redundant backup lighting functionality for all tailgate positions (e.g., closed, open, and removed). Exemplary systems may include both vehicle static body structure mounted backup lamps and tailgate structure mounted backup lamps for providing the backup lighting redundancy.

A light-emitting device (20) includes a light-emitting region (140). The light-emitting region (140) includes a plurality of light-emitting units (142) and a plurality of light-transmitting units (144), and each of the plurality of light-transmitting units (144) is located between the light-emitting elements (142) adjacent to each other. The light-emitting region (140) is located on a side of one surface (outer surface (202)) of a base material (200) having light-transmitting properties and has an inclination with respect to the one surface (outer surface (202)). The base material (200) is rear glass of an automobile. The base material (200) partitions a region outside a mobile object (region (RG1)) from a region inside the mobile object (region (RG2)).

Various embodiments of the present invention provide a hybrid backup lamp having a backup light and a laser or LED warning light integrated therewith.

An illuminations system placed on a rear cargo van door providing auxiliary lighting to improve safety. Light modules are attached to the rear cargo van doors so that when the doors are opened an amber warning light is illuminated along the edge of the open cargo van door pointing rearward. A task light preferably is incorporated in the light modules to provide downward task lighting. The lighting modules are attached adjacent edges of the rear cargo van doors without permanent modification to the cargo van.
