Abstract
An external lighting apparatus delivers various messages through selective lighting by applying a lighting function to the exterior of a vehicle. The apparatus includes a light source module with a plurality of light sources and a light guide in which light emitted from the light sources is incident. The light guide reflects the incident light so that the light travels in different areas. The apparatus has a light cover composed of a plurality of transmission parts into which the light, travelling in different areas via the light guide, is incident. The light is emitted to different lighting areas through each transmission part to create a plurality of illumination images.
