§17C-15-20. Multiple-beam road-lighting equipment -- Requirements generally.
Except as hereinafter provided, the head lamps or the auxiliary driving lamp or the auxiliary passing lamp or combinations thereof on motor vehicles other than a motorcycle, motor-driven cycle or moped shall be so arranged that the driver may select at will between distributions of light projected to different elevations and such lamps may, in addition, be so arranged that such selection can be made automatically, subject to the following limitations:
(a) 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 three hundred and fifty feet ahead for all conditions of loading.
(b) There shall be a lowermost distribution of light, or composite beam, so aimed and of sufficient intensity to reveal persons and vehicles at a distance of at least one hundred 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 eyes of an approaching driver.
(c) Every new motor vehicle, other than a motorcycle, motor- driven cycle or moped, registered in the state after January 1, 1952, 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.
