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