The Dog Island Lighthouse on Dog Island in Foveaux Strait is New Zealand's tallest lighthouse, and one of its oldest.  It is notable for its masonry construction, and is a work example by an engineer who was prominent at the time.  The lighthouse employed the first revolving beam in New Zealand, and the unique original light apparatus was in use for 60 years.  Dog Island Lighthouse is one of the most distinct lighthouses in New Zealand, with only two others having stripes painted on it for better daytime-conspicuity.  The lighthouse is registered by Heritage New Zealand as a Category I structure, and the adjacent lighthouse keepers cottage has a Category II registration.  Originally operated by three lighthouse keepers, the structure has since 1989 been remote controlled from Maritime New Zealand's Wellington office, with Dog Island since having been uninhabited.  Dog Island Lighthouse has twice featured on New Zealand stamps.

The Pass A L'Outre Light (or Pass a Loutre Light) is a defunct lighthouse in the Birdfoot Delta in Louisiana, located near the mouth of the Mississippi River.  Erected to mark the then-active entrance to the river, it was abandoned as that channel silted up.  It has been in the path of several noteworthy hurricanes, and was heavily damaged.  It is on the Lighthouse Digest Doomsday List, and is critically in danger.  The lighthouse is at the center of a nature preserve.
