Several states in the U.S. (CO, CT, GA, ME, NM, RI, TX, UT) have already enacted some form of lighting code and some codes are better than others.  The goals are :

•Enhance the quality of life for all

•Allow redress for neighbor’s bad light

•Set a uniform code for all outdoor lighting

•Enhance safety and security by reducing glare

•Reduce or eliminate light pollution

•Enable views of the night sky by the public and by astronomers

Hawai'i needs a state-wide code that would require all state funded roadway and highway lighting to be full cutoff and wattages reduced once all roadway light is shining downwards. All beach front lighting should not spill out onto waterways or the ocean.

Hawai'i needs local county codes that would require all local roadway lighting to be full cutoff and all other outdoor lights over 1800 lumens to be fully shielded and aimed straight downward. Flood lights should require shielding and should not be aimed higher than 45 degrees from vertical. Motion sensors should be encouraged for security lighting. Ordinances and codes need enforcement fines to be effective.
