This category is for sites about the regulation of lighting via lighting laws, codes or ordinances. A lighting code or ordinance is a local code defining the allowed levels of lighting often set by local council planning departments or similar local bodies. State or national laws may also set restrictions on light pollution however it is generally accepted that permitted levels should vary from region to region making local government the main legislature on light pollution. For further information, see the sites in this category and its subcategories, or contact your local government body (e.g.:council), astronomical society or light-pollution campaign group to find out if a law or ordinance is being implemented locally.
