Every evening the Bay Lights turn the San Francisco Bay Bridge into a shimmering, mesmerizing nighttime LED light sculpture.

The Bay Lights is 1.8 miles wide and 500 feet high LED light sculpture. Inspired by the Bay Bridge’s 75th Anniversary, artist Leo Villareal  creates a never repeating, dazzling display of 25,000 LED white lights through March 2015 across the western span of the Bay Bridge.

The Bay Lights is a monumental light sculpture inspired by the 75th anniversary of the Bay Bridge, now called the Willie L. Brown, Jr. Bridge. Artist Leo Villareal networked 25,000 individually programmable, white LEDs made by Philips to create complex algorithms and patterns across the western span of the bridge. This contemporary art piece is the world’s largest LED light sculpture.

Installation of the LED system took place at night to minimize impact on motorists. A crew of 8-10 electricians worked Monday through Friday, 8:00 p.m. to 5:00 a.m., to install the piece.

Grand Re-Lighting

The Bay Lights was removed from the bridge in March 2015 (per the original permit) to allow Caltrans to perform maintenance on the cables. ILLUMINATE raised $4 million to ensure The Bay Lights re-installation, in time to shine for Super Bowl 50 in February 2016. The final raise was made possible by Bay Area philanthropist Tad Taube, whose $2 million challenge grant inspired other donors to give the remaining amount needed to re-install the sculpture.

The grand re-lighting was January 30, 2016. The re-installed sculpture uses all new, robust LEDs designed to withstand harsh environmental conditions over time.

The Bay Lights artwork has been be gifted to the State of California for ongoing stewardship. Following the precedent of the necklace lights that were added to the suspension cables in 1986 and became a fixture of the Bay Bridge in 1989, The Bay Lights will become a permanent part of the western span, maintained by Caltrans.
