(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 three hundred and fifty feet ahead for all conditions of loading;(2) 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 so as to strike the eyes of an approaching driver; and(3) Every motor vehicle, other than a motorcycle or motor-driven cycle, registered in this State after January 1, 1949 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. Such 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.1955 (49) 89; 1949 (46) 466; 1952 Code Section 46-547; 1962 Code Section 46-547.
