Maine Lighthouse Museum, 1 Park Drive in Rockland, will host author Jay Dolin for a signing of “Brilliant Beacons” on Thursday, August 4, from noon to 4 p.m. Dolin’s book, released this April, traces the evolution of America's lighthouse system from its earliest days, detailing the political, military and technological issues that had to be overcome to build the system of lights that helped the U.S. become a global merchant power.
