People up and down the country pull out all the stops to ensure that their house is the biggest and brightest in their neighbourhood by adorning their homes with huge displays of shining seasonal lights.
Due to attracting fans, many of these displays feature a charity collection box to raise money for those in need.
The TV show Britain's Craziest Christmas Lights features four of the most dazzling displays in the UK. We dread to think how high their electricity bills must be!
Malcolm Molloy, 55, and his wife Wendy, 51, of Bromsgrove have already raised a staggering 50K for charity, with the cost of their Christmas lights reaching 25K!
Canterbury based Greengrocer Stan Truelove, 58, has illuminated his entire street with a display costing around 80K, but Stan's efforts have already raised 40K for charity.
The twinkling display on the home of Dave, 79, and Carol, 67, Edwards, of Rickmansworth cost around 5K, but their charity pot is now worth a whopping 40k!
Wayne Skinner, 25, from Chesterfield, with the help of his dad John, have raised a shining £1,200 for charity with their 6K spectacular light show.
Britain's Craziest Christmas Lights is aired tonight at 9pm on Channel 5.
