Abstract
A handle assembly includes a bezel having a handle cavity defined by a cavity wall and an open front providing access to the handle cavity. The bezel has a slot through the cavity wall and a lamp assembly is mounted to the bezel proximate the slot. The lamp assembly includes a housing and a light pipe held by the housing, where the light pipe includes a first leg extending along a primary axis and a second leg extending along a secondary axis generally perpendicular with respect to the primary axis. The second leg has a lens along an inner surface of the second leg, wherein light is directed through the light pipe along the primary axis to a primary reflective surface provided at the intersection of the first and second legs. The primary reflective surface directs light along the second leg toward the lens.
