"We've had a high rate of failure for these lights," said David Carmody, City of Chattanooga Deputy Chief Operating Officer.
In 2011, the city entered a $6 million dollar contract with Global Green Lighting. Five thousand LED lamps were installed on downtown streets.
Since then, the city reports that 14% of them have failed.
"When you're looking at 600-plus lights that have failed, that's quite a bit of money," Carmody said.
Each time a light goes out, Carmody said it costs an additional $225 to replace it.
That adds up to an extra $135,000.
"We're addressing those problems as they come up, and we're trying to find a solution moving forward," said Carmody.
"The reason the lights in Main Terrain park are not burning is solely the responsibility of Mayor Berke," said Don Lepard, owner of Smart City Management. "Even though Berke canceled our contract and we have no obligation to do so, we continue to pay the costs for repairing or replacing any light that does not work properly when we are informed of a problem."
The city encourages people to call Chattanooga 311 to report any outages.
