Brighten these shorter days with fantastic light displays and other merrymaking. Spirits Promise Equine Rescue Program’s “Holiday Farm Lights” fundraiser stars Santa and his reindeer from December 17-19. Wölffer Estate’s “Lighting of the Vines” makes wine tastings and nibbles all the more festive. The Dickens Carolers perform during the Sag Harbor Historical Society’s “Light Up the Harbor” on December 20.
