"Light Up the Night," an event planned by the San Francisco Bicycle Coalition and the San Francisco Municipal Transportation Agency, will be held from 6 to 7 p.m.
During the one-hour giveaway, Bicycle Coalition volunteers will hand out safety literature and offer the reminder that by state law riders need to have a front white light and rear red reflector or light when riding at night.
The free lights will be given away along popular bike routes: Valencia and Cesar Chavez streets at St. Luke's Hospital, Market Street and Duboce Avenue, Howard and Eighth streets, Polk and California streets, and McAllister and Webster streets.
"The SFBC is promoting safe night riding by distributing free bike lights to those who can't afford or don't have access to them," Bicycle Coalition Program Director Andy Thornley said. "Bicycle lights are an important safety item and we want everyone to have them, especially during the winter months when it gets darker earlier."
