Abstract

A lighted exterior mirror system for a vehicle includes an exterior mirror assembly and a signal light disposed in the exterior mirror assembly. The signal light includes at least one light emitting diode. The signal light is configured to emit a light pattern and the light pattern is defined at least between a forward leading edge and a rearward leading edge. The forward leading edge of the light pattern forms a forward angle that is in the range of about zero degrees to about 45 degrees relative to the side of a vehicle equipped with the lighted exterior mirror system, and the rearward leading edge of the light pattern forms a rearward angle that is in the range of about zero degrees to about 15 degrees relative to the side of the equipped vehicle.
