So despite living on an 'island' you still are going to have a neighbor, and it sounds like a nagging one at that. Then again, you could be buying front-row tickets for... something.

US - Pigeon Point Lighthouse

Pigeon Point Light Station, California, United States:
Perched on a cliff on the central California coast, 50 miles south of San Francisco, the 115-foot Pigeon Point Lighthouse, one of the tallest lighthouses in America, has been guiding mariners since 1872. Its five-wick lard oil lamp, and first-order Fresnel lens, comprised of 1,008 prisms, was first lit at sunset, November 15, 1872. The lens stands 16 feet tall, 6 feet in diameter, and weighs 8,000 pounds. It sits in a lantern room that had been constructed at the Lighthouse Service's general depot in New York before being shipped around the Horn. Although the original Fresnel lens is no longer in use, the lighthouse is still an active U.S. Coast Guard aid to navigation using a 24 inch Aero Beacon. - California State Parks




Needs some paint.

This is a little more dramatic photo of the lighthouse:


Once per year at the Pigeon Point Lighthouse they shut down the weak insipid modern (presumably electric) light and switch over the the 5 kerosene lamps and fresnel lens of the original, as it was 135 years ago.

Last night was the night, and it's really quite a sight. When they fire it up there's really a collective sense of "whoa!" from the audience (which was WAY bigger than I expected - I probably had to park a mile away and I was there an hour early). - MumbleyJoe's photos, Flickr
Go read the rest on how he managed to take the photo. Here is some more on the light source:
The lantern room of the tower is equipped with the original first-order Fresnel lens. Infrequently used today, the lens has 24 flash panels, is composed of 1008 hand-polished lenses and prisms, and is capable of producing over 500,000 candlepower illumination. It was manufactured by the Henry-LePaute company in Paris, and was first lit at Pigeon Point at sunset on November 15, 1872.

Originally the tower was equipped with a lamp that burned refined lard oil. In 1888, that lamp was replaced with a mineral oil (kerosene) lamp. To produce Pigeon Point's assigned characteristic of 1 white flash of light every 10 seconds, the four ton lens rotated one time every four minutes. When observed from a distance, this resulted in the appearance of one white flash of light every 10 seconds. The lens rotation was originally powered by a clockwork and weight. In 1926 the lighthouse was provided electricity. Modern innovations were incorporated and the kerosene IOV lamp was replaced by a 1000 watt bulb, the clockwork by an electric motor, and an electrically operated fog signal was eventually installed. - Wiki
Lighthouses are of course meant to be lit, not that you would know it with 99% of lighthouse photos taken during the day!

Australia - Sugarloaf Point Lighthouse

Sugarloaf Point Lighthouse, Australia:
The Sugarloaf Lighthouse was completed in 1875, ten years after it was first recommended a light be placed to highlight the nearby Seal Rocks. It was originally intended to place the light on Seal Rocks but landing was difficult the proposition was abandoned.

The tower is constructed of brick, rendered and painted white. Also constructed were three adjoining cottages, various outbuildings, the construction of the road from Bungwahl, and a 1500 foot long jetty which was used to land some 1800 tons of building supplies and materials.. - Lighthouses of Australia Inc (Click for more photos and details)

You don't often see short lighthouses. Seems that the tall ones get all the attention. Actually, they are kind of cool. I guess these are for you if you like lighthouses and are afraid of heights.

Montauk Point Lighthouse

Montauk Point Lighthouse, United States:
Welcome to the Montauk Point Lighthouse, the oldest lighthouse in New York State. The Lighthouse was authorized by the Second Congress, under President George Washington in 1792. Construction began on June 7, 1796 and was completed on November 5, 1796. This historic landmark has been part of Long Island's land and seascape for over 200 years and still serves as an active aid to navigation. - Montauk Point Lighthouse


Construction on the lighthouse was authorized by the Second United States Congress, under President George Washington in 1792. Construction began on June 7, 1796, and was completed on November 5, 1796. The lighthouse and adjacent Camp Hero were heavily fortified with huge guns during World War I and World War II. Those gun emplacements and concrete observation bunkers (which are also at nearby Shadmoor State Park) are still visible.

It was the first lighthouse in New York State, and is the fourth-oldest active lighthouse in the United States. The tower is 110' 6" high. The current light, equivalent to 2,500,000 candle power, flashes every 5 seconds and can be seen a distance of 18 nautical miles (33 km). - Wikipedia
