Abstract
A lens is provided for use in a vehicle interior ambient light device. The lens provides a beam of light that is narrower and is directed to a desirable position on different vehicle models and versions of those models. The lens includes an upper section having a shape that is a section of a frustum of a cone. The lens also includes a lower section having a shape of a frustum of an oblique cone with an oval base. Textured surfaces of the sides of the frustum of the lower section prevent the emission of stray light beams.
