Section 347.11 - Headlamp specifications for mopeds and motor bicycles The headlamps on mopeds or motor bicycles may be of the single-beam or multiple-beam type but in either event shall comply with the following requirements and limitations:
(1) The headlamp shall be an electric headlamp and the current shall be supplied by a wet battery and electric generator, by a current-generating coil incorporated into the magneto or by a generator driven directly by the motor by means of gears, friction wheel, chain or belt.(2) The headlamp shall display a white light of sufficient illuminating power to reveal any person, vehicle or substantial object at a distance of 200 feet ahead and shall be so adjusted or operated that the glaring light rays therefrom are not directed into the eyes of the driver of any oncoming vehicle. No headlamp shall have any type of decorative covering that restricts the amount of light emitted when the headlamp is in use. This subsection does not apply to any type of decorative covering originally equipped on the vehicle at the time of manufacture and sale.(3) If the moped or motor bicycle is equipped with a multiple-beam headlamp, the upper beam shall meet the minimum requirements set forth in sub. (2) and the lowermost beam shall meet the requirements applicable to a lowermost distribution of light as set forth in s. 347.10(2) (b).(4) If the moped or motor bicycle is equipped with a single-beam lamp, such lamp 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, projects higher than the level of the center of the lamp from which it comes.1983 a. 243; 1995 a. 346.
