These headlighting systems control the headlamp beams according to the running state of a vehicle at night in order to provide optimal illumination. They have two functions: to control the range of illumination according to vehicle speed and to control beam direction in response to the steering. Two optical systems were developed to realize these functions. One system uses two movable mirrors in each headlamp, while the other system uses a movable lens installed in front of the projector lamp. According to photometric data analysis done in our laboratory, bath systems improve visibility on curved roads substantially. It was also found that they are effective in limiting glare projected onto oncoming vehicles.
