A liquid crystal beam broadening apparatus for use with a left side or a right side vehicle headlight producing a beam , the apparatus comprising: a control unit ; a liquid crystal driver circuit responsive to a control signal from said control unit; and a liquid crystal beam broadening device responsive to a drive signal provided from said driver circuit to broaden said vehicle headlight beam in a horizontal direction, wherein said control unit comprises a signal input either indicative of a left or right steering direction or indicative of presence or absence of an on-coming vehicle and modulates said control signal so that said device broadens horizontally the beam of said headlight said signal input is either indicative of one of a left or a right steering direction corresponding to the location on the left or right side on the vehicle of said headlight or indicative of absence of an on-coming vehicle and maintains or reduces a horizontal spread of the beam of said headlight when said steering direction signal input is either indicative of one of a left or a right steering direction opposite to the location on the left or right side on the vehicle of said headlight or indicative of presence of an on-coming vehicle, in the case the signal input is a steering direction signal input, a vehicle headlight driver for modulating an intensity of the vehicle headlight, wherein said control unit is further responsive to said steering direction signal to increase the intensity of the vehicle headlight when said signal input is indicative of one of a left or right steering direction corresponding to the location on the left or right side on the vehicle of said headlight . a control unit ; a liquid crystal driver circuit responsive to a control signal from said control unit; and a liquid crystal beam broadening device responsive to a drive signal provided from said driver circuit to broaden said vehicle headlight beam in a horizontal direction, wherein said control unit comprises a signal input either indicative of a left or right steering direction or indicative of presence or absence of an on-coming vehicle and modulates said control signal so that said device broadens horizontally the beam of said headlight said signal input is either indicative of one of a left or a right steering direction corresponding to the location on the left or right side on the vehicle of said headlight or indicative of absence of an on-coming vehicle and maintains or reduces a horizontal spread of the beam of said headlight when said steering direction signal input is either indicative of one of a left or a right steering direction opposite to the location on the left or right side on the vehicle of said headlight or indicative of presence of an on-coming vehicle, in the case the signal input is a steering direction signal input, a vehicle headlight driver for modulating an intensity of the vehicle headlight, wherein said control unit is further responsive to said steering direction signal to increase the intensity of the vehicle headlight when said signal input is indicative of one of a left or right steering direction corresponding to the location on the left or right side on the vehicle of said headlight . <EOS>
