Abstract

The invention relates to an optical device and to a headlighting assembly including an optical device. An optical device includes a body of a transparent material arranged to receive light at at least one light input portion. At least a portion of the light is reflected at an outer surface of the body due to total internal reflection. A non-transparent housing is provided to at least partially cover the body. The body is held within the housing by protrusions arranged to abut against the outer surface.
