1. An automatic vehicle exterior light control system comprising:

  • a processor configured to effect automatic operation of the light control system as a function of an ambient light value, wherein said ambient light value is a weighted average of a plurality of ambient light level readings acquired from a photo transducer;

    a controller configured to generate an exterior light control signal if the light control system is operational as a function of the presence of an atmospheric condition of interest, wherein said controller is further configured to distinguish between reflections off of a highly reflective surface and reflections off of atmospheric conditions of interest based on input from at least one imager; and

    wherein an exterior light control output of said controller is in a first state when reflections off of a highly reflective surface are detected and said exterior light control output is in a second state when reflections off of atmospheric conditions of interest are detected.
