Abstract

A light pipe assembly includes a lamp assembly and a light pipe. The lamp assembly has a housing that holds a light source configured to emit light. The light pipe is elongated between an attachment end and an opposing distal end. The attachment end is received in the housing of the lamp assembly. The light pipe receives light emitted by the light source. Additionally, the light pipe includes surface elements that are configured to permit the light to emanate from the light pipe between the attachment and distal ends. The surface elements are arranged in a pattern that provides a predetermined distribution of light emanating from the light pipe.
