Dog Lights for Night Walks: How to Keep Your Dog Seen After Dark
Once the clocks go back, the evening dog walk happens in the dark for most of us. In December it can be dark before 4pm in much of the UK, so the after-work walk, and often the school-run walk too, is pitch black for months.

We walk two Chow Chows, Nala and Storm. Between their dark coats and the unlit streets near us, Storm in particular can disappear completely a few metres away. A light on your dog is the simplest fix we know of, and it doesn't need to cost much.
This guide covers the kit we actually use on our own night walks, plus the types of dog light worth knowing about and how to choose between them.

The three types of dog light
There are really only three options, and plenty of dog owners end up using two of them together.
Clip-on lights. A small LED that straps onto a collar, harness or lead. Cheap, easy to move between dogs, and the easiest place to start.
Light-up collars. The whole collar glows, so your dog can be seen from the side as well as the front and back. Often called LED dog collars.
Light-up harnesses. A harness with LEDs built in, so the light sits across your dog's back and chest. Handy if you'd rather have everything in one piece of kit.
What we use
The thing we like most about this collar is the fit. It comes long (ours measured about 70cm) and you cut it down to size, so there's no measuring your dog's neck before you buy. Nala is a large fluffball of a Chow Chow and it fitted her perfectly with no trimming at all. Storm is a little smaller, so we cut about an inch off hers, and it clipped back together without any trouble.
It charges over USB-C, and the port has a rubber seal that adds some water resistance, which matters on wet winter walks. The USB cable is in the box. Mountain Paws quote up to 16 hours from a charge, which is plenty for a good week of evening walks.
It's bright, too. On Storm's black coat it shines straight through her thick fur, which is exactly what we were hoping for with a Chow. There are four colours (blue, pink, red and white), each with a constant and a flashing mode.
It sits alongside your dog's normal collar rather than replacing it, so keep the ID tag on the usual one.
Best for: Dogs that run off-lead in the dark, where you want to see them from any direction.
These are small clip-on lights on a silicone strap that loops around a collar or harness. Mountain Paws make a USB-C rechargeable version too, but we went for the battery ones for a simple reason: you get two for the price of one rechargeable, and we have plenty of CR2032 coin cells kicking around the house.
There are four colours (blue, pink, red and white) and two modes for each, so eight settings in all. They're bright, and the rubber strap with its hook and loop holds them on securely. They weigh just 14g, so the dogs don't notice them.
They're not just for collars and harnesses, either. We often strap one to our Mountain Paws Stretch Dog Lead.
Mountain Paws quote 15 to 30 hours on white and 30 to 50 hours on the colours. If you'd rather never buy a battery again, the rechargeable version is £9.99 for one.
Best for: Trying a dog light for the first time, or kitting out two dogs cheaply.
Lighting up the dog is half the job. Your phone torch does the job at a push, but not when you're hunting for a poo in the grass, holding the lead and rummaging for a bag all at once. A head torch keeps both hands free.
We use the Lifesystems Intensity 300. It puts out up to 300 lumens, charges over USB, and runs for up to 38 hours on its lowest setting (around 2 hours on full power). It's rated IPX6, so heavy rain won't stop it. The red light mode is useful when you want to see without dazzling someone coming the other way.
Best for: Anyone walking dogs on unlit streets or paths.
Light-up harnesses: one we haven't tried
We haven't used a light-up harness ourselves. Our setup is a clip-on light on the harness the dogs already wear, and that works for us. But if you'd rather have everything in one, here's what to look for:
USB charging, so you're not buying batteries all winter
An adjustable fit, especially across the chest
A water-resistance rating, because it will get wet
Lights on the sides as well as the back
The one that keeps coming up is the Noxgear LightHound. It uses fibre optic strips rather than a single LED, so it lights up across the chest and back, with 8 colours and 6 flashing or fading modes. It charges over USB, runs for up to 12 hours, has adjustable neck and chest straps, and can go in the washing machine. It comes in four sizes (small to extra large) and costs from about £44, depending on size.
It's well reviewed on Amazon, but we want to be clear that we haven't tested it. It's also more than four times the price of a pair of clip-on lights, so we'd only go for it if the all-in-one fit really matters to you.
How to choose a dog light
Where should a dog light go?
Somewhere it can be seen from as many directions as possible. We worried that fur would swallow a collar light on a Chow, but the Mountain Paws collar shines through Storm's thick coat without any trouble. A clip-on light on the back of the harness adds a second point of light that's easy to spot from behind.
Flashing or constant?
Flashing grabs a driver's attention, which is why it's the better choice near roads. A constant light is easier to follow if your dog is off-lead in a field, because you can track where it's going. All the dog lights here do both, so use flashing on the lane and constant once you're through the gate.
Rechargeable or batteries?
Rechargeable lights save you buying coin cells. Battery lights last longer between changes and are cheaper to buy in the first place. We use one of each: the rechargeable collar and the battery clip-ons. If you charge your phone every night, you'll cope fine with a rechargeable dog light.
Water resistance
The Mountain Paws lights are described as water-resistant rather than waterproof, and don't quote an official rating. They're built for rain and wet grass. If your dog heads straight for the river, keep an eye on it. The Lifesystems head torch is rated IPX6, which means it copes with heavy rain.
Frequently asked questions
What colour LED light is best for dogs?
The light is mostly for people to see your dog, rather than for your dog, so pick the colour that stands out best where you walk. White is the brightest and the easiest for drivers to spot. Blue and pink are easy to recognise as a dog rather than a bike or a car. Many owners avoid red near roads, because drivers associate a red light with the back of a vehicle. If you walk two dogs, giving each one a different colour makes it easy to tell who's who in the dark.
Are LED lights safe for dogs?
The small lights made for dog collars and harnesses aren't bright enough to be a problem, and they sit below your dog's eye line. As with any light, avoid shining a bright torch directly into your dog's eyes. If your dog is unsure about a flashing light at first, start on constant and let them get used to it at home.
Do dogs need lights at night in the UK?
There's no law that says your dog must wear a light. But on unlit lanes and paths, and especially near roads, a light makes your dog much easier for drivers, cyclists and you to see. For the price of a couple of coffees, it's an easy one.
How long do dog light batteries last?
It depends on the light and the mode. The Mountain Paws rechargeable collar quotes up to 16 hours from a charge, which gets us through about a week of evening walks. The coin cell Dog Safety Lights quote 15 to 30 hours on white and up to 50 hours on the colours.
Should my dog wear a light on a lead walk too?
Yes, if you're anywhere near a road. A dog on a lead can still step out from behind you, and a driver will often see the dog's light before they see you.
Our pick for most people
If you're starting from scratch, get the Mountain Paws Dog Safety Lights. Two lights for £9.99 is hard to argue with, and they move easily between collar, harness and rucksack. If your dog runs off-lead in the dark, add the Rechargeable Dog Collar Light so you can see them from any direction. That's exactly how we walk Nala and Storm.
If you've got a light you swear by on your own night walks, tell us in the comments. We'd genuinely like to hear what works for your dog.
