The statutes and regulations use the words "lamps" and "lights" interchangeably. (Perhaps the word “lamp” harkens back to the days of horseless carriages?) Because of this, the print index to the statutes may be more helpful than keyword searching online. Look under the term “motor vehicles” and then for the subdivision “Lights and Lighting.” Once you get to the appropriate RSA chapter, look at the beginning of the chapter which gives a list of subdivisions and shows you the context of all of the statutes in that section.
