A. Every motor vehicle shall be equipped with at least two headlamps emitting a white light with at least one lamp on each side of the front of the motor vehicle on the same level and as far apart as practicable. The headlamps shall comply with the requirements and limitations set forth in this chapter.

B. Every headlamp upon every motor vehicle shall be located at a height of not more than fifty-four (54) inches nor less than twenty-two (22) inches to be measured as set forth in subsection B of Section 12-202 of this title.

C. The headlamps on motor vehicles 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:

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 six hundred (600) 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 two hundred (200) feet ahead; and

3. 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.

D. Every motor vehicle 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 headlamps is in use, and shall not otherwise be lighted.
