When the residents of Lyon, France, survived the plague in 1647, they celebrated by lighting candles and offering tributes to the Virgin Mary. More than three centuries later, the display has evolved into a sweeping lights party that draws millions of tourists to the town in early December. Now, with the help of Alliance Française Washington, Georgetown will undergo a similar transformation, hosting five different light displays from artists around the world. For her piece, “Zodiac,” Belgium’s Chloé Yaiche draws inspiration from the night sky and NASA satellite imagery. Elsewhere, visitors can get in on the action by texting their own transmissions to Fabien Bourdier’s “Larsen3G” or switching on and off the lights in Travesías de Luz’s “Floating Lights.” Stop by tonight for the opening event, or cruise through anytime to Dec. 20, when the light party officially ends. The opening night party takes place at 9 p.m. Friday at Malmaison, 3401 K St. NW. $10. Installations are on view Dec. 13 to Dec. 20, 6 p.m. to 10 p.m., at locations around Georgetown.
