Every motor vehicle driven during the period from 1/2 hour after sunset to 1/2 hour before sunrise, and whenever rain, snow, or fog shall interfere with the proper view of the road so that persons and vehicles on the way are not clearly discernible at a distance of 1000 feet ahead, shall display at least 2 lighted lamps on the front; provided, however, that one suitable lighted lamp on the front of a motorcycle shall be sufficient. The headlamp shall throw sufficient light ahead within the travelled portion of the way to make clearly visible all vehicles, persons, or substantial objects within a distance of 200 feet, except that the headlamps of motorcycles shall be sufficient if they make clearly visible objects within a distance of 150 feet. No headlamp shall be used unless it is approved by the director and is equipped with a proper lens or other device designed to prevent glaring rays. All headlamps on every motor vehicle shall be located at a height of not more than 54 inches nor less than 24 inches from the ground on an unladen vehicle.

I. No person other than a sworn law enforcement officer with power of arrest shall operate a vehicle equipped with blue colored lights, except in the case of a service technician driving the vehicle in connection with servicing or maintaining the vehicle or as provided under paragraph II.
II. No person other than a sworn law enforcement officer with power of arrest or an emergency response employee or volunteer of a city, town, or village district or the federal government or an employee of a private ambulance service contracted with a city, town, or village district shall operate a vehicle equipped with a rear-facing blue colored light, except in the case of a service technician driving the vehicle in connection with servicing or maintaining the vehicle.
266:78-i Use of Amber Lights.
Vehicles authorized to use amber colored warning lights authorized by RSA 266:78-h may only illuminate the warning lights when their duties require them to be stopped or parked on or immediately adjacent to a way at a road, water, or sewer line construction or maintenance site in a manner that may impede or cause a hazard to traffic, when actively engaged in the delivery of United States mail, or when actively engaged in snow removal or ice treatment or when entering or leaving a way during plowing operations, or during repair or placement of official traffic control devices, pavement marking, or escorting an oversize load or slow moving vehicle, or in the case of wreckers and emergency road service vehicles when maneuvering through congested traffic to reach a disabled vehicle, providing roadside service, loading or unloading a vehicle, or when transporting a disabled vehicle.
Every new motor vehicle sold and driven upon a way, other than a tractor truck, shall carry on the rear, either as a part of the tail lamps or separately, 2 red reflectors, except that every motorcycle, moped and motor-driven cycle shall carry at least one reflector.

Every motor vehicle and trailer or any combination of vehicles, when on the ways of this state at night, shall have on the rear thereof, and to the left of the axis thereof, one lamp, displaying a red light visible for a distance of at least 1000 feet to the rear of such vehicle, and a white light illuminating the registration plate of such vehicle so that the characters thereon shall be visible for a distance of at least 50 feet.

Any vehicle 80 inches or more in overall width, if not otherwise required by this chapter, may be equipped with not more than 5 identification lamps showing to the front which shall emit an amber or white light without glare and with not more than 3 identification lamps showing to the rear which shall emit a red light without glare.
