§321.  Multiple beam road lighting equipment

Except as hereinafter provided, the head lamps or the auxiliary driving lamps or the auxiliary passing lamp or combinations thereof on motor vehicles other than motorcycles or motor-driven cycles shall be so arranged that the driver may control the selection between the distributions of light projected to different elevations, subject to the following requirements and limitations:

(1)  There shall be an uppermost distribution of light, or composite beam, so aimed and of such intensity as to reveal persons and vehicles at a distance of at least 500 feet ahead for all conditions of loading.

(2)  There shall be a lowermost distribution of light, or composite beam, so aimed and of such intensity to reveal persons and vehicles at a distance of at least 150 feet ahead; and on a straight level road under any condition of loading none of the high intensity portion of the beam shall be directed to strike the eye of an approaching driver.

(3)  Every new motor vehicle, other than a motorcycle or motor-driven cycle, registered in this state after January 1, 1955, which has multiple beam road lighting equipment shall be equipped with a beam indicator, which shall be lighted whenever the uppermost distribution of light from the head lamps is in use, and shall not otherwise be lighted.  Said indicator shall be so designed and located that when lighted it will be readily visible without glare to the driver of the vehicle so equipped.
