| 摘要 |
A highway vehicle is equipped with an additional directed light for illuminating the area to the side and/or rear of the vehicle where another approaching vehicle will pass by the first vehicle. The additional light helps the driver of the other vehicle see the area into which he or she is driving. The additional light is used at night when the driver of the other vehicle may have vision impaired by the headlights of the vehicle equipped with the additional light and by the fact that the other vehicle's headlights have been reduced to their "low beam" setting. Circuitry for automatically turning the additional light on and off may be provided. Adjustable mounting for the additional light may be provided.
