      (1)   The time from sunset to sunrise;
      (2)   At any other time when, due to insufficient natural light or unfavorable atmospheric conditions, persons, vehicles, and substantial objects on the street or highway are not discernible at a distance of one thousand feet ahead;
      (3)   At any time when the windshield wipers of the vehicle are in use because of precipitation on the windshield.

   (c)   Whenever in this chapter a requirement is declared as to the mounted height of lights or devices, it shall mean from the center of such light or device to the level ground upon which the vehicle stands.
   (d)   Notwithstanding any provision of law to the contrary, no law enforcement officer shall cause the operator of a vehicle being operated upon a street or highway to stop the vehicle solely because the officer observes that a violation of subsection (a)(3) of this section has been or is being committed or for the sole purpose of issuing a ticket, citation or summons for a violation of that subsection, or causing the arrest of or commencing a prosecution of a person for a violation of that subsection.
   (e)   Whoever violates this section is guilty of a minor misdemeanor.
