Several Cities incorporate local lighthouses into their official 'seals'. These include Fernandina Beach FL (Amelia Island) and Mukilteo Washington. You can see these logos on the "lighthouse oddities" page: http://www.lighthousekeepers.com/lh_odd.htm

Many companies are also including lighthouses in advertising: Canon color copiers, and others.
