Abstract
A light pipe assembly includes a light pipe having one or more first crush ribs extending outwardly from an outer surface of the light pipe. The light pipe assembly further includes a light pipe housing having one or more second crush ribs extending into a cavity of the light pipe housing. When the light pipe is positioned in the cavity of the light pipe housing, the light pipe is retained in the light pipe housing by the one or more first crush ribs and the one or more second crush ribs. The one or more first crush ribs come in contact with and press against the one or more second crush ribs when the light pipe is positioned in the cavity of the light pipe housing.
