It's been revealed that tens of thousands of pounds have been saved as a result of Exeter's car parks going green.
The city council has replaced bulbs in three of them with LED ones and they've saved more than £35,000 in their first year of operation.
They say Mary Arches, Harlequins and Cathedral and Quay are now also safer because the lighting's better.
