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

    a processor configured to receive and analyze the image data to detect one or more red light sources and to further analyze each detected red light source to determine if each respective red light source is detected for a predetermined time period,based on a determination that the respective red light source is not detected for the predetermined time period, the processor is further configured to;

    (i) determine that the respective red light source is a flashing red stop light, and (ii) generate a signal indicating that an illumination level of exterior lights of the vehicle should be reduced when a brightness of the flashing red stop light exceeds a brightness threshold regardless of an absence of any other vehicles in the imaged scene.
