(3)Rear lamps. Every motor vehicle, trailer, semitrailer, pole trailer and any other vehicle which is being drawn in a train of vehicles shall be equipped with at least one (1) rear lamp mounted on the rear, which, when lighted, shall emit a red light plainly visible from a distance of five hundred (500) feet to the rear. However, any antique automobile, as defined under Section 27-19-47, and any street rod, as defined under Section 27-19-56.6, may be equipped with one or more rear lamps that have been modified to emit a blue, violet or purple light resembling rear lamps appearing on some American automobiles originally manufactured in the 1940s and 1950s. Either a rear lamp or a separate lamp shall be so constructed and placed as to illuminate with a white light the rear registration plate and render it clearly readable from a distance of fifty (50) feet to the rear. Any rear lamp or tail lamps, together with any separate lamp for illuminating the rear registration plate, shall be so wired as to be lighted whenever the head lamps, cowl lamps or fender lamps are lighted.
