1. A mirror assembly for a vehicle comprising:
- a mirror housing having an opening located at a lower portion of the housing;
a mirror secured to the mirror housing;
a light source mounted within the mirror housing; and
a waveguide mounted within the mirror housing and extending through the housing from an input end to an output end, wherein the input end is oriented proximate the light source to receive light emanating from the light source and the output end is located within the opening in the mirror housing such that the output end forms both a lower, exterior surface portion of the mirror housing and a front, exterior surface portion of the mirror housing, and wherein light entering the input end of the waveguide from the light source is conducted by internal reflection within the waveguide and exits the mirror housing through the output end of the waveguide.

Abstract
A mirror assembly for a vehicle with a light is provided. The mirror assembly includes an exterior mirror assembly that is attached to the vehicle. A light source is removably positioned inside the exterior mirror assembly. A waveguide is positioned to transmit light from the light source to a location outside the exterior mirror assembly. The light source is secured to a light holder which is positioned inside and attached to the exterior mirror assembly. The light holder is configured to efficiently couple light from the light source to the waveguide.
