At SillySanta you'll find Christmas light up jumpers – also known as light-up Christmas jumpers or Christmas jumpers with lights – for women, men and kids. Match the whole family for this year's Christmas card and let everyone glow! From cheeky novelty knits to bold, battery-powered designs that twinkle on demand, there's a light-up jumper for every taste in our collection.
Why our christmas light up jumpers steal the show
The magic here isn't the knit pattern, it's the lights built right into it. Soft LEDs sit across the front of each design and flash in patterns through the evening, so a jumper that looks like an ordinary cosy knit when it's switched off turns into the brightest thing in the room the moment you flick it on. That's the wow you can't get from a printed jumper.
People search for these in a dozen ways – christmas jumper with lights, christmas jumpers that light up, even flashing christmas jumpers – and they all land on the same idea: a festive knit that actually glows. Ours give you that twinkle without the faff, and they pair happily over a shirt or a roll-neck when the temperature drops. If you're browsing wider festive looks beyond christmas t shirts and plain knits, a light-up jumper is the piece that gets the room talking.
The lights: flash patterns, modes and where they sit
This is the part the photos never quite capture. The LEDs aren't a single steady glow – they flash and cycle in patterns, so you get movement across the design rather than a flat string of bulbs. A small controller tucked into the seam lets you switch between a gentle twinkle and a faster, busier flash, then off again, all in a couple of seconds.
Where the lights sit depends on the design. On some they trace the outline of a Christmas tree so the whole shape lights up branch by branch. On others they string along a row of festive bulbs across the chest, ring a wreath, or pick out a single bright spot like a reindeer's nose. The lights are stitched into the fabric itself, not clipped on top, so they stay put and the jumper still reads as a proper knit. If you want light up jumpers for christmas that look as good switched off as they do lit, this is the range.
Light up xmas jumpers for women, men and kids
We split the range across the whole family, so there's a glow for everyone.
Women's
Our ladies light up christmas jumper styles are made to layer over jeans or a skirt for the office party, the family meal or a Christmas market wander. If you've been hunting for a women's light up xmas jumper that's festive without tipping into fancy dress, the softer twinkling designs sit perfectly between fun and flattering.
Men's
A light up christmas jumper for men is the easy win at any gathering – pull it on, switch on the lights, and you're the most festive bloke at the bar without trying. Mens christmas light up jumpers in the bolder, busier flash modes are the ones that get the biggest laugh at the office do.
Kids'
Children love these most of all. Kids' light up jumpers are brilliant for Christmas jumper day at school, the nativity, festive playdates and the family photo, and the magic of a jumper that sparkles like fairy lights keeps the mood merry all season. Light up the whole crew and the Christmas card sorts itself.
The practical bit: batteries, washing and safety
This is where we go further than most. Here's everything you'd want to know before you buy.
-
Batteries: each jumper runs on two standard CR2032 batteries, which are easy to find and which we sell, so you can pop fresh ones in before the big day. They don't arrive with batteries fitted.
-
Cool and safe: the LEDs are low-voltage and stay cool to the touch, woven into the fabric rather than sitting on top, which is exactly why they're fine for children to wear all evening.
-
Washing: they're machine washable. Just unclip and remove the battery pack first, wash as normal, and the jumper comes out good as new.
-
Discreet when off: the controls tuck into the seam and the lights disappear into the knit when switched off, so it wears like any normal Christmas jumper between glow sessions.
Where christmas light up jumpers fit in the wider range
These are the show-offs of our festive knitwear, but they're one corner of a much bigger collection. If a glowing design is a step further than you fancy this year, the full range of christmas jumpers covers everything from classic Fair Isle to the loud and silly, in matching sets for the whole household. The light-up ones are simply the brightest way to do it, the jumper you reach for when you want to out-sparkle the tree.
