I wish I was there to see it's opening ceremony, heard it was amazing despite the unstable San Francisco weather. Bay Lights is installed on the north side of the western span of the bridge (attached with 60,000 zip ties) between San Francisco and Yerba Buena Island. The project has been privately funded, and is still raising the final quarter of their $8 Million goal. It is estimated the lights will use only $30 of electricity a day or $11,000 over 2 years.
