(a) (1) Every motor vehicle other than a motorcycle, road roller, road machinery or farm tractor shall be equipped with at least two (2) and not more than four (4) headlights, with at least one (1) on each side of the front of the motor vehicle. No nonemergency vehicle shall operate or install emergency flashing light systems, such as strobe, wig-wag, or other flashing lights within the headlight assembly or grill area of the vehicle; provided, however, that a school bus may operate a flashing, wig-wag lighting system within the headlight assembly of the vehicle when the vehicle's visual stop signs are actuated for receiving or discharging school children.
