Abstract

A lighting device is provided that includes a housing containing a light emitting portion of a light emitting diode and a terminus of a fiber optic bundle such that light emission from the light emitting diode is communicated along the optical fibers. The fiber optic bundle has a flattened distal portion with a cross-sectional array of layers of optical fibers. A diffusing layer is attached to the fiber optic bundle overlying the flattened distal portion. The lighting device, upon being overlaid with a graphic and surrounded by a frame through which the graphic is visible, provides a vehicle lighting assembly securable to a vehicle substrate. The vehicle light assembly is particularly well suited for vehicle exterior badging, kick plates and vanity lighting within the vehicle passenger compartment.

Claims
