§ 46.2-1020. Other permissible lights.

Any motor vehicle may be equipped with fog lights, not more than two of which can be illuminated at any time, one or two auxiliary driving lights if so equipped by the manufacturer, two daytime running lights, two side lights of not more than six candlepower, an interior light or lights of not more than 15 candlepower each, and signal lights.

The provision of this section limiting interior lights to no more than 15 candlepower shall not apply to (i) alternating, blinking, or flashing colored emergency lights mounted inside law-enforcement motor vehicles which may otherwise legally be equipped with such colored emergency lights, or (ii) flashing shielded red or red and white lights, authorized under § 46.2-1024, mounted inside vehicles owned or used by (a) members of volunteer fire companies or volunteer rescue squads, (b) professional fire fighters, or (c) police chaplains. A vehicle equipped with lighting devices as authorized in this section shall be operated by a police chaplain only if he has successfully completed a course of training in the safe operation of a motor vehicle under emergency conditions and a certificate attesting to such successful completion, signed by the course instructor, is carried at all times in the vehicle when operated by the police chaplain to whom the certificate applies.

Unless such lighting device is both covered and unlit, no motor vehicle which is equipped with any lighting device other than lights required or permitted in this article, required or approved by the Superintendent, or required by the federal Department of Transportation shall be operated on any highway in the Commonwealth. Nothing in this section shall permit any vehicle, not otherwise authorized, to be equipped with colored emergency lights, whether blinking or steady-burning.

§ 46.2-1030. When lights to be lighted; number of lights to be lighted at any time; use of warning lights.

A. Every vehicle in operation on a highway in the Commonwealth shall display lighted headlights and illuminating devices as required by this article (i) from sunset to sunrise, (ii) during any other time when, because of rain, smoke, fog, snow, sleet, insufficient light, or other unfavorable atmospheric conditions, visibility is reduced to a degree whereby persons or vehicles on the highway are not clearly discernible at a distance of 500 feet, and (iii) whenever windshield wipers are in use as a result of fog, rain, sleet, or snow. The provisions of this subsection, however, shall not apply to instances when windshield wipers are used intermittently in misting rain, sleet, or snow.

B. Not more than four lights used to provide general illumination ahead of the vehicle, including at least two headlights and any other combination of fog lights or other auxiliary lights approved by the Superintendent, shall be lighted at any time. However, this limitation shall not preclude the display of warning lights authorized in §§ 46.2-1020 through 46.2-1027, or other lights as may be authorized by the Superintendent.

C. Vehicles equipped with warning lights authorized in §§ 46.2-1020 through 46.2-1027 shall display lighted warning lights as authorized in such sections at all times when responding to emergency calls, towing disabled vehicles, or constructing, repairing, and maintaining public highways or utilities on or along public highways, except that amber lights on vehicles designed with a ramp on wheels and a hydraulic lift with a capacity to haul or tow another vehicle, commonly referred to as "rollbacks," need not be lit while the vehicle is in motion unless it is actually towing a vehicle.

D. The failure to display lighted headlights and illuminating devices under the conditions set forth in clause (iii) of subsection A of this section shall not constitute negligence per se, nor shall violation of clause (iii) of subsection A of this section constitute a defense to any claim for personal injury or recovery of medical expenses for injuries sustained in a motor vehicle accident.

E. No demerit points shall be assessed for failure to display lighted headlights and illuminating devices during periods of fog, rain, sleet, or snow in violation of clause (iii) of subsection A of this section.

F. No citation for a violation of clause (iii) of subsection A of this section shall be issued unless the officer issuing such citation has cause to stop or arrest the driver of such motor vehicle for the violation of some other provision of this Code or local ordinance relating to the operation, ownership, or maintenance of a motor vehicle or any criminal statute
