1. An imaging system for a vehicle, comprising:

  • an imager configured to image a scene external and forward of the vehicle and to generate image data corresponding to acquired images; and

    a processor configured to receive and analyze the image data to detect the presence of a light source and to identify whether such light source is a light of another vehicle;

    wherein;

    when a light source is detected, said processor is configured to generate a signal that is used to control exterior lights of the vehicle to temporarily modulate at least a portion of an illumination pattern projected from the exterior lights to have a particular modulation pattern at least in the direction of the detected light source,after generating the signal, said processor is configured to analyze the image data subsequently received to detect whether the light source has a modulation pattern corresponding to the modulation pattern of the exterior lights,when the light source does have such a modulation pattern, said processor is configured to determine that the light source is a reflective object and not a light of another vehicle, andwhen the light source does not have such a modulation pattern, said processor is configured to determine that the light source may be a light of another vehicle.
