1.    The headlamp or headlamps upon every motor-driven cycle may be of the single-beam or multiple-beam type.

2.    Every headlamp or headlamps on a motor-driven cycle must be of sufficient intensity to reveal a person or a vehicle at a distance of not less than one hundred feet [30.48 meters] when the motor-driven cycle is operated at any speed less than twenty-five miles [40.23 kilometers] per hour and at a distance of not less than two hundred feet [60.96 meters] when the motor-driven cycle is operated at a speed of twenty-five or more miles [40.23 or more kilometers] per hour, and at a distance of not less than three hundred feet [91.44 meters] when the motor-driven cycle is operated at a speed of thirty-five miles [56.33 kilometers] per hour.

3.    In the event the motor-driven cycle is equipped with a multiple-beam headlamp or headlamps the upper beam must meet the minimum requirements set forth above and may not exceed the limitations set forth in subsection 1 of section 39-21-20 and the lowermost beam must meet the requirements applicable to a lowermost distribution of light as set forth in subsection 2 of section 39-21-20.

4.    In the event the motor-driven cycle is equipped with a single-beam lamp or lamps the lamp or lamps must be so aimed that when the vehicle is loaded none of the high-intensity portion of light, at a distance of twenty-five feet [7.62 meters] ahead, projects higher than the level of the center of the lamp from which it comes.
