A mirror assembly security system suitable for use in a vehicle comprises an
exterior
mirror assembly including a reflective element and a positioning device for adjustably
positioning said reflective element. A light module is positioned substantially
within the assembly and includes an enclosure having a light-transmitting opening
generally facing downward when the exterior mirror assembly is mounted to a side
of the vehicle. The light module includes a light source and a light-directing
surface at least partially surrounding the light source. The light module projects
a pattern of light from a bottom portion of the assembly to illuminate a ground
area adjacent the vehicle in order to create a lighted security zone when said
light source is electrically powered.
