}} Plum Beach Light (Lighthouse), built in 1899, is a sparkplug lighthouse in North Kingstown, Rhode Island. The lighthouse was built using pneumatic caisson engineering. A granite base was added in 1922. The light was deactivated in 1941 when the first Jamestown Bridge was built. The light became dilapidated until 1999 when the Friends of Plum Beach Lighthouse received ownership of the lighthouse. The lighthouse is now listed on the National Register of Historic Places. In 2003 the Plum Beach Lighthouse's exterior was completely restored and its beacon re-activated soon after and is now licensed as a Coast Guard Private Aid to Navigation. The Friends of the Plum Beach Lighthouse designed, submitted and introduced an official License Plate to be distributed to any Rhode Island private passenger registration. The extremely popular plates have sold over 7000 sets since they were released in July 2010. The plate can be seen at http://www.pblplate.org == History == Construction on the Plum Beach Lighthouse began in 1897 by contractors using the “pneumatic caisson” method which was cutting edge technology at the time. This was achieved by dropping the caisson in the water down to the bay's floor, then pumping out the water which was replaced by concrete. The lighthouse was then built upon the newly hardened concrete. Granite rip rap was then placed underwater around the base of the caisson for support. When the lighthouse was first built, it was simply protruding from the water.
