When upon any highway in this State, every motorcycle shall at all times exhibit at least one lighted lamp showing a white light, commonly known as a driving lamp, visible for at least five hundred feet (500') in the direction the motorcycle is proceeding. All other motor vehicles shall, during the period from sunset to sunrise, or at any other time when visibility is so limited as to require the use of lights for safety, exhibit two (2) such lighted driving lamps showing white lights or lights of a yellow or amber tint visible for at least five hundred feet (500') in the direction the motor vehicle is proceeding. Parking lamps may be used in addition to but not in lieu of any such driving lamps. Every motor vehicle, trailer or semi-trailer shall also exhibit at least two (2) lighted lamps, commonly known as taillamps, which shall be mounted on the left rear and right rear of the vehicle so as to throw a red light visible for at least five hundred feet (500') in the reverse direction; except, that a motorcycle or a truck tractor or road tractor manufactured before January 1, 1968, need be equipped with only one such lamp.
Either a tail lamp or a separate lamp shall be so constructed and placed as to illuminate with a white light a rear registration plate when required and render it clearly legible from a distance of fifty feet (50') to the rear. Any taillamp or taillamps, together with any separate lamp or lamps for illuminating a rear registration plate shall be so wired as to be lighted whenever the driving lamps or auxiliary driving lamps are lighted.
