This year, the town council has purchased all new lights, including twinkly lights for the trees and Christmas tree in front of the town hall.
The lights were switched on by mayor, Jim Broomfield, and Magdalen College School student, Josh Taylor, 15, who has helped the community.
There were also performances from local schools, Brackley Rock Choir and Josie and the Outlaw.
Councillor Fiona Baker said: “The response from the public has been amazing. Everyone has loved them.”
