Whenever a motor vehicle is being operated on a roadway or shoulder adjacent thereto during the times specified in Section 56-5-4450, 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:

(1) Whenever the driver of a vehicle approaches an oncoming vehicle within five hundred 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;

(2) The lowermost distribution of light or composite beam specified in item (2) of Section 56-5-4770 shall be aimed to avoid glare at all times, regardless of road contour and loading; and

(3) Whenever the driver of a vehicle follows another vehicle within two hundred feet to the rear, except when engaged in the act of overtaking and passing, such driver shall use a distribution of light permissible under this section other than the uppermost distribution of light specified in item (1) of Section 56-5-4770.
