Abstract

The invention is related to a rear view mirror assembly with a mirror base attached to a vehicle and a mirror head. The mirror head is formed to host a reflective element and an approach light, the approach light is positioned in the lower side of the mirror assembly to light up an area adjacent to the vehicle. The approach light includes a mask to allow the projection of the pattern adjacent to the vehicle. In more detail the invention is related to a way to project a pattern adjacent to a vehicle.
