Christmas is likely to be a lot different this year because of the coronavirus pandemic, and it means we will not have the same large events for light switch-ons as in previous years.
The Commercial Road event has always been particularly popular with families who are looking to start their Christmas celebrations early.
Here are a selection of photos from the switch-on in recent years – do you feature in our gallery?
