Whenever a motor vehicle is being operated on a roadway or shoulder adjacent thereto during the time between 30 minutes after sunset and 30 minutes before sunrise, the driver shall use a distribution of light, or composite beam, directed high enough and of sufficient intensity to reveal persons and vehicles at a safe distance in advance of the vehicle, subject to the following requirements and limitations.
(a) Whenever the driver of a vehicle approaches an oncoming vehicle within 500 feet, such driver shall use a distribution of light or composite beam so aimed that the glaring rays are not projected into the eyes of the oncoming driver, and in no case shall the high-intensity portion that is projected to the left of the prolongation of the extreme left side of the vehicle be aimed higher than the center of the lamp from which it comes at a distance of 25 feet ahead, and in no case higher than a level of 42 inches above the level upon which the vehicle stands at a distance of 75 feet ahead.
