The St Peter Port Christmas Lights Charity has launched a campaign to repair the infrastructure that maintains its festive lights every year.
Wires, fixings, and power supplies will be restored across the town.
The charity says the changes are needed to ensure the display continues to be safe in the future.
The project should be finished within three to five years - some work has already been done on Mill Street.
The charity says the upgrades could cost up to £25,000 in total, but it is currently looking to raise a minimum of £10,000 for next year.
