Visibility

Every automobile operated during the period from one half an hour after sunset to one half an hour before sunrise, and during any other period when visibility is reduced by atmospheric conditions so as to render dangerous further operation without lights being displayed, shall display at least two lighted white headlamps with at least one mounted at each side of the front of the vehicle or if parked within the limits of a way at least one white or amber light on the side of the automobile nearer the center of the way, and every motorcycle so operated at least one white headlamp and every such motorcycle with a sidecar attached, in addition, one such light on the front of the sidecar, and every motor truck, trailer and commercial motor vehicle used solely as such, having a carrying capacity of three tons or over, in addition, an amber light attached to the extreme left of the front of such vehicle, so attached and adjusted as to indicate the extreme left lateral extension of the vehicle or load, which shall in all cases aforesaid be visible not less than two hundred feet in the direction toward which the vehicle is proceeding or facing; provided, that an automobile need display no light when parked within the limits of a way in a space in which unlighted parking is permitted by the rules or regulations of the board or officer having control of such way. Every motor vehicle and trailer so operated shall be equipped with two rear lights mounted one at each side of the rear of the vehicle so as to show two red lights from behind and a white light so arranged as to illuminate and not obscure the rear number plate and shall be equipped with two stop lights mounted and displayed in a like manner of a type complying with minimum standards for construction and performance as the registrar may prescribe; provided, however, that a two-wheeled motorcycle, an antique motor car and a farm tractor need be equipped with only one such rear red light and one suitable stop light in addition to the number plate illuminator; and provided, further, that a trailer having a gross weight of three thousand pounds or less which does not obscure the required lights of the towing vehicle need be equipped with only one such rear red light and one white light so arranged as to illuminate and not obscure the rear number plate. No motor vehicle so operated shall mount or display a flashing, rotating or oscillating light in any direction except pursuant to section seven E of this chapter; provided, however, that this shall not apply to the use of rear directional signals nor to the proper use of vehicle hazard warning signals as provided for by this section. In no event, however, shall the registrar prohibit any commercial auto parts dealer, motor vehicle repair shop or station from selling, offering for sale or installing quartz-halogen headlamps which receive a certificate of approval from the American Association of Motor Vehicles Administrators or which meet the standards of the Canadian Standard Association (CSA) nor shall any provision of this section prohibit any person from using, purchasing or installing a quartz-halogen headlamp as herein described.
