Works are being carried out in the Ballalough housing estate
Some street lights in Castletown have been switching off 30 minutes earlier than usual.
Manx Utilities, which is in charge of the street lights around the town, says there has been a 'cable fault' in the Ballalough Estate and lights are now on a 'temporary' timer.
The estate will be running at a 'slightly' different time to other areas in Castletown for the next two weeks until the work is completed.
