Illuminated car park signs around Norwich are expected to be out of order until Monday.
The signs, which show people how many spaces there are in car parks around the city, suffered a technical fault.
Norfolk County Council said its maintenance contractor is working to source replacement parts to fix the fault, and should have the signs working again on Monday.
