(1) Every said head lamp or head lamps on a motor-driven cycle shall be of sufficient intensity to reveal a person or a vehicle at a distance of not less than 100 feet when the motor-driven cycle is operated at any speed less than 25 miles per hour and at a distance of not less than 200 feet when the motor-driven cycle is operated at a speed of 25 or more miles per hour, and at a distance of not less than 300 feet when the motor-driven cycle is operated at a speed of 35 or more miles per hour.

(2) In the event the motor-driven cycle is equipped with a multiple beam head lamp or head lamps the upper beam shall meet the minimum requirements set forth above and shall not exceed the limitations set forth in R.S. 32:321(1), and the lowermost beam shall meet the requirements applicable to a lowermost distribution of light as set forth in R.S. 32:321(2).

(3) In the event the motor-driven cycle is equipped with a single beam lamp or lamps, said lamp or lamps shall be so aimed that when the vehicle is loaded none of the high intensity portion of light, at a distance of 25 feet ahead, shall project higher than the level of the center of the lamp from which it comes.
