Section 34
SEC. 34. Every motor vehicle of more than one meter of projected width, in use on any public highway, whether in motion or not, shall bear two lamps visible from the front one on each side, which not later than one-half hour after sunset and until at least one-half hour before sunrise, shall both be lighted. While the vehicle is in motion on a level the lights shall render the person of a man dressed in dark clothing visible at a distance of not less than thirty meters ahead and the light thrown forward or ahead of the motor vehicle shall be white light. Additional lamps and lights may be carried. The use of a headlight or headlights which concentrate and project the light or any portion thereof into a beam, unless said light is so adjusted or equipped that the projected beam of light therefrom shall not be uncomfortably visible for more than one meter above the surface of the highway at a distance of twenty meters or more, is prohibited within the limits of cities, municipalities or barrios and on any highway when less than fifty meters from an approaching vehicle. Every motor vehicle shall further, during the hours aforesaid, bear in the rear a lamp throwing a white light upon the number plate issued for such vehicle, which light shall render the number legible for a distance of at least eighteen meters in the direction from which such motor vehicle is proceeding. The hours herein fixed within which such lamps shall burn shall not exempt operators from the obligation of lighting such lamps or causing the same to be lighted at earlier or later hours or times, when on account of atmospheric or weather conditions or other phenomena, the use of such motor vehicles upon public highways might otherwise be dangerous or unsafe. Every motor vehicle of less than one meter of projected width shall be subjected to the preceding provisions of this section, except that but one head lamp and one tail lamp will be required thereon. Additional lamps may be carried provided they comply with the preceding provisions of this section. Every other vehicle, of whatever style, kind, make, character, or nature, when upon a highway during the hours aforesaid, whether in motion or not, shall bear one or more lights so arranged that same shall be visible from the front and the rear of such vehicle. The provisions of this section shall not apply to vehicles parked or standing on well lighted streets of cities and municipalities.
