The 1849 Palmer's Island Lighthouse appears on the city of seal of New Bedford, Massachusetts. The motto "Lucem Diffundo" means "I Diffuse Light" or "I Spread the Light." It has a triple meaning.
1) The lighthouse itself served to "spread the light."
2) New Bedford was a center of the whaling industry and provided the whale oil that fueled our lighthouses and other lights around the country for many years.
3) New Bedford's city fathers were predominately Quakers. The Quakers referred to themselves as "Children of the Light." Their mission was to spread the "Light of Christ" to the world.
Palmer's Island Lighthouse is owned by the City of New Bedford, and it was restored and relighted back in 1999. It's currently undergoing another refurbishing. At this writing, the lantern has been removed and is undergoing restoration on shore.
The plans also include repointing of the interior and exterior walls, repair and cleaning of the steel stairs, the installation of new windows and hatches, and the installation of new solar powered lighting apparatus.
