San Francisco, United States - June 27, 2025 A dazzling 4.1-mile laser rainbow lit up the city skyline on June 27, as captured in a video by X user Rafael Prado Jr. “Happy Pride Month from San Francisco,” Rafael wrote. “Filmed on Friday the 27th at 10pm in San Francisco at the San Francisco laser rainbow Pride Flag ceremony.” The footage shows vibrant laser beams stretching across Market Street, piercing the night fog with brilliant rainbow colors. Nicknamed the “Gaysers,” the installation ran from the R-Evolution statue at Embarcadero Plaza all the way toward the Castro. Organizers called it the world’s largest Pride flag, created entirely with light. The lasers formed a breathtaking display to mark Pride Weekend, drawing spectators and filling the city with bold color and celebration.
