For almost a decade, it has dazzled drivers, locals and visitors alike thanks to a spectacular light installation.
"More than 20 million people have a chance to enjoy the bay lights," said Ben Davis with Illuminate/TBL360 Project.
This year, the light show on the western span of the bridge may go dark. Davis explains why.
"The lights up there are suffering. They are failing at a rate faster than we can replace them," said Davis.
At least $11 million is needed in donations to update the bay lights art display and keep them up for a decade.
"The fundraising, the way we're working to do it here at illuminate, is to find 10 very generous patrons who can provide $1 million each to get us to the $10 million mark," said Davis.

Davis hopes supporters can help raise enough money by March to replace the bay lights.
"March 5 is the day the bay lights go dark," said Davis. "The sooner the funds can come it, the sooner the lights can come back."
Davis the new so called "TBL360 project" would bigger and brighter. With 48,000 new LED lights.
"We're actually doubling up the number of LEDs. And try to make the lights accessible to the entire Bay Area.
But until that happens, Davis says much more help is needed.
"This is a group effort of the Bay Area. It's a philanthropic moment," said Davis.
To help replace the lights on the Bay Bridge, the plan is also to raise $1 million of the total $11 million cost through crowd funding.
That particular fundraising effort kicks off March 5. Davis says the goal is to have the new display up and running by Dec.
