New Hampshire
At present there is no statewide outdoor-lighting legislation in New Hampshire. In 2003-04, the New Hampshire Citizens for Responsible Lighting attempted to get an outdoor-lighting bill passed in the state legislature, without success.
Recently another volunteer group has formed to try to effect change. For more information, contact Barbara O'Connell (nhdarksky@charter.net).
Here's a list of cities and towns in New Hampshire that have adopted outdoor-lighting regulations:
Bedford
Bethlehem
Brookline (see Section 2300 on page 85)
Danbury
Francestown
Londonderry
Ossipee
Plaistow
Seabrook
