No statewide law

Wisconsin

Last checked 2026-09-23

Wisconsin has no statewide outdoor lighting or dark-sky statute; its lighting-related statutes (e.g., Wis. Stat. 347.24(1)(am) and 347.26(11)) govern vehicle lighting, not fixed outdoor fixtures. Some municipalities regulate lighting on their own.

Municipal codes

  • Madison: City council adjusted outdoor lighting rules to align with the city's International Dark Sky Community status.
  • Town of Amnicon: Town ordinance restricts outdoor lighting to preserve dark skies.
