More than 170 illuminated tractors and trucks have paraded through the Yorkshire Wolds.
The fourth annual charity run set out from Driffield on a 30-mile route around the surrounding villages on Saturday evening.
The event, which raises money for blood cancer charities, was started by Nicola Roper, who has twice been treated for the disease.
“This is our fourth year and each year it gets better and better – the drivers put so much effort into it,” she said.
