The humble streetlight doesn’t look like a particularly attractive target for theft. But in Los Angeles, a mind-boggling 27,000 miles of copper wire connect those lights to the power grid — and thieves are tearing that wire out at an alarming rate. Public employees can’t keep up with repairs, leaving frustrated neighborhoods in the dark for months on end.
The sun-drenched city has recently discovered a promising new solution: It’s swapping out traditional streetlights for solar-powered versions that are not attached to the larger power system and thus have no copper wire to steal. Instead, the new lights are equipped with batteries that fill up on solar energy during the day and discharge it after dusk falls.
“It’s been tremendously successful,” said Miguel Sangalang, executive director and general manager of LA’s Bureau of Street Lighting.
While copper-wire theft isn’t a new plight for LA, it’s become more prevalent in recent years as rising prices have made it more lucrative to sell the stolen metal. In the last decade, theft and vandalism have jumped from representing just a few percent of the Bureau of Street Lighting’s service requests to 40% today, according to a spokesperson for the department. Since 2020, the city has spent over $100 million repairing such damage. On Reddit, residents complain of “pitch black” neighborhoods that feel unsafe.
The city isn’t about to replace all of its more than 220,000 streetlights with solar. So far, it’s only deployed around 1,100 of the new fixtures, and plans to install at least 400 more this fiscal year. The Bureau of Street Lighting is still figuring out its long-term strategy, but for now, it’s focused on rolling out solar lights where they can immediately do the most good: areas with lots of theft.
“[We’re] testing it in incremental steps,” Sangalang said. “But we see ourselves going into it much harder and much faster in the near future.”
Other U.S. cities are thinking along the same lines. Clark County, home to Las Vegas, began testing solar streetlights last summer after dropping more than $1.5 million over two years to fix vandalized lights. St. Paul, Minnesota, decided to install the city’s first solar streetlights this year, fed up after spending over $2 million in 2024 on repairs only for thieves to strike again days later. San Jose, California, which had about 1,000 streetlights out due to copper theft in early July, is currently planning a pilot, pending funding availability.
These are small-scale experiments, but they still reduce planet-warming greenhouse gas emissions by introducing more clean energy into major cities. One of the solar lighting companies that LA is working with estimates that deploying 10 of its sun-powered streetlights in Europe would cut carbon emissions by 60 metric tons over four decades — the same pollution footprint as seven flights around the Earth.
LA’s quest to create a “maintenance-free zone”
Inspired by a suggestion from a field electrician, LA began testing off-grid solar lights in 2022 with $200,000 in grants from the city’s innovation fund. In early 2024, the city rolled out its first concentrated, large-scale deployment of 106 solar lights in the Van Nuys neighborhood — a hotspot for theft that is located far from the Bureau of Street Lighting’s headquarters downtown.
“We’d spend two hours on the road trying to do a repair if we had to go back and forth,” Sangalang said.
The goal in Van Nuys was to create a “maintenance-free zone,” said a spokesperson for the Bureau of Street Lighting. It’s working: In a year and a half, the department hasn’t had to deal with a single instance of damage related to theft and vandalism. Among community members, “the sentiment continues to be that they’re great and that we need to see more of them in the city,” said LA Councilmember Imelda Padilla, a Democrat who represents Van Nuys.
With that track record, the city has since rolled out hundreds more solar lights in the Watts, Boyle Heights, and Historic Filipinotown neighborhoods.
“This is one of those things where, across the board, whether you care about the environment or not, lighting is the best deterrent to crime, right?” Padilla said. “It makes it so that families and single women and children can enjoy the Southern California weather late into the night.”
