(11) Lighting Devices and Reflectors.
(a) In general. All lighting devices and reflectors required by applicable Federal Motor Vehicle Safety Standards when the particular motorcycle was originally manufactured and such devices required by Massachusetts General Law or Rules and Regulations applicable to the particular motorcycle inspected shall be securely attached to the vehicle and capable of performing their design functions. Lenses must be intact, clean, unobstructed and free from cracks. All lenses on stop lamps, tail lamps, turn signal lamps and reflectors must be approved by the Society of Automotive Engineers (SAE) and as evidence of such of approval indicate the symbol "SAE" on the lens. All replacement lighting devices and reflectors shall meet applicable Federal Motor Vehicle Safety Standard's at the time they were installed. No additional lamp, reflective device or other motor vehicle equipment shall be installed that impairs the effectiveness of lighting equipment required under these regulations. Two or more lamps, reflectors or items of associated equipment may be combined if the requirements for each lamp, reflector or item of associated equipment are met.
(b) Headlamps. Each motorcycle shall be equipped with at least one and not more than two white headlamps whose beam shall be checked in accordance with the specifications provided by the Registrar. The motorcycle headlamp shall be mounted on the front of the motorcycle on the vertical centerline, except that if two headlamps are used, they shall be symmetrically distant from the vertical centerline and equal in height. The height of the headlamps measured from the road surface to the center of the lamp shall be not less than 22 inches nor more than 54 inches. Headlamps on motorcycles manufactured in the year 1986 or later shall throw sufficient light ahead to make clearly visible all vehicles, persons or substantial objects upon the roadway within a distance of 350 feet on a straight highway of uniform grade under normal atmospheric conditions. Headlamps on motorcycles manufactured before 1986 shall throw sufficient light ahead to make clearly visible all vehicles, persons or substantial objects upon the roadway within a distance of 115 feet under the same conditions.
(c) Tail lamps and stop lamps. Each motorcycle shall be equipped with at least one red tail light and at least one red stop lamp. The motorcycle tail lamp and stop lamp shall be mounted on the rear of the motorcycle on the vertical centerline, except that if two are used, they shall be symmetrically distant from the vertical centerline and of equal height. The height of the tail lamps and stop lamps measured from the road surface to the center of the lamp shall be not less than 15 inches nor more than 72 inches. Stop lamps shall be activated with the application of front or rear brakes. Tail lamps shall be activated when the headlamps are activated. Tail lamps and stop lamps shall be visible under normal night time conditions at a distance of 500 feet and stop lamps shall be visible in normal sunlight at a distance of 200 feet.
(d) Plate light. Each motorcycle shall be equipped with a white light so arranged as to illuminate the rear number plate so that it is plainly visible at a distance of 60 feet. Such light shall not emit a tailing glare.
(e) Reflectors. Each motorcycle shall have at least one rear red reflector mounted on the vertical center line except that, if two are used, they shall be symmetrically distant from the vertical center line and of equal height. The reflector height above the road surface measured to the center of the reflector shall not be less than 15 inches, nor more than 60 inches. Note: reflector(s) may be combined with other rear lamps. Motorcycles manufactured on or after January 1, 1968 shall be equipped with two red side reflectors mounted on each side at or near the rear of the motorcycle and shall be equipped with two amber side reflectors mounted on each side at or near the front of the motorcycle. The side reflector height above the road surface measured to the center of the reflector shall not be less than 15 inches, nor more than 60 inches.
(f) Turn signals. Each motorcycle manufactured on or after January 1, 1973 shall be equipped with front and rear turn signal lamps. Front turn signal lamps shall be amber mounted at or near the front of the motorcycle on each side of the vertical center line at the same height and shall have a minimum horizontal separation distance (measured from center of lamps) of 16 inches. Minimum edge to edge separation distance between turn signal lamp and head lamp shall be four inches. Rear turn signals shall be red or amber mounted on each side of the vertical center line at the same height and having a minimum horizontal separation distance (measured from center of lamps) of nine inches. All turn signal lamps shall be mounted at a height from the road surface of not less than 15 inches nor more than 83 inches. Turn signal lamps shall flash at a rate of 60 to 120 flashes per minute. The turn signal lamp activating control shall be positioned so as to be operated without removing the hand from the handlebar and shall properly indicate right and left when so switched. Turn signal lamps shall be visible at a distance of 200 feet under normal daylight conditions. Every motorcycle shall be equipped with a device to permit the front and rear directional signals to flash simultaneously if originally equipped by the manufacturer.
(g) Auxiliary driving lamps and fog lamps. These lamps are not required, however, if so equipped shall be aimed in accordance with specifications provided by the Registrar. Reject motorcycle if:
1. Auxiliary equipment is placed in front of or obstructs any required lamp or reflector.
2. Fog lamps operate with high beam of headlamp.
3. Auxiliary driving lamps operate with low beam of headlamp or alone.
4. Equipped with more than two fog lamps or more than two auxiliary driving lamps.
5. Auxiliary driving lamps or fog lamps are not mounted at a height above the road surface between 12 inches and 42 inches.
