§ 28-430. Tail lamps, reflectors.

(a)

Every motor vehicle and every motor-drawn vehicle shall be equipped with at least two (2) rear lamps, not less than fifteen (15) inches or more than forty-eight (48) inches above the ground upon which the vehicle stands, which when lighted will exhibit a red light plainly visible from a distance of five hundred (500) feet to the rear; provided, however, that the rear lamps may be mounted higher than forty-eight (48) inches on any vehicle carrying inflammable liquids as cargo. Either these rear lamps or a separate lamp shall be so constructed and placed as to illuminate with a white light the rear registration marker and render it clearly legible from a distance of fifty (50) feet to the rear. When the rear registration marker is illuminated by an electric lamp other than the required rear lamps, all such lamps shall be turned on or off only by the same control switch at all times.

(b)

Every motorcycle or motorized bicycle registered in this state, when operated on a street, shall also carry at the rear, either as part of the rear lamp or separately, at least one approved red reflector, which shall be of such size and characteristics and so maintained as to be visible during the times when lighted lamps are required from all distances within three hundred (300) feet to fifty (50) feet from such vehicle when directly in front of a motor vehicle displaying lawful undimmed head lamps.

(c)

Every new passenger car, new commercial motor vehicle, motor-drawn vehicle and omnibus with a capacity of more than six (6) passengers registered in this state, when operated on a street, shall also carry at the rear at least two (2) approved red reflectors, at least one at each side, so designed, mounted on the vehicle and maintained as to be visible during the times when lighted lamps are required from all distances within five hundred (500) to fifty (50) feet from the vehicle when directly in front of a motor vehicle displaying lawful undimmed head lamps. Every such reflector shall meet the requirements of this division and shall be mounted upon the vehicle at a height not to exceed sixty (60) inches nor less than twenty-four (24) inches above the surface upon which the vehicle stands.
