Best bike lights for kids

With so many options on the market, it can be tricky to know which bike lights are best for your child. We’ve tested and researched a range of lights to find the ones that are safe, easy to use, and designed to work on smaller bikes.

Below you’ll find our top picks for the best kids bike lights, with options to suit every age, riding style, and budget.

Fixing a rear bike light to the seat post of a small pedal bike or balance bike can be really tricky – especially when the seat post is set at its lowest position. And even if you do manage it, the light often ends up so low that it’s hard for anyone to see, or it gets hidden under a dangling coat.

The Knog Plus is a clever wearable option that solves this problem. This is one of the best bike lights for younger riders because you can clip them onto your child’s coat or hood, or be mounted on handlebars, forks, or seat posts – either vertically or horizontally. With so many fitting choices, you’re bound to find somewhere to mount it.

In wearable mode, the natural movement of your child helps catch the attention of passing motorists, as the light bobs up and down. It’s not just for cycling either – the Knog Plus also works brilliantly for walking, scooting, or running, making it a great choice for active families.

The Knog Plus is lightweight (just 17 g), fully waterproof, and charges directly via USB – no cables required. A practical, flexible, and fun choice if you’re looking for one of the best bike lights for kids that really stands out.

We reviewed an earlier model of Knog wearable lights which you can read about here.

FAQs on best bike lights for kids

Not sure which bike lights are best for your child? These FAQs cover everything you need to know before buying. From legal requirements to practical features, we’ve got you covered.

Do kids legally need bike lights?

Yes. By law, all cyclists – including children – must have a white front light and a red rear light when riding between sunset and sunrise.

By UK law, every bike must have:

  • A white front light
  • A red rear light
  • A red rear reflector
  • Amber pedal reflectors (on bikes manufactured after 1st October 1985)

These lights and reflectors are essential for making your child visible to drivers and other road users.

Before heading out on darker mornings and evenings, check that your child’s bike has the correct setup. Choosing the best bike lights for kids helps ensure your child is visible and safe.

If you're new to cycling with your children, find out more in our guide on Cycling with kids: everything you need to get started.

What’s the difference between bike lights for adults and kids?

Most bike lights are designed for adult bikes, which means they can be too large, heavy, or expensive for children.

The best kids bike lights are lightweight, easy to fit on smaller frames, simple for children to operate, and often more affordable.

Where should I fit bike lights on a child’s bike?

Front lights usually attach to the handlebars, while rear lights are fixed to the seat post.

On very small bikes or balance bikes, the rear light can sit too low, so a wearable option (on a coat, for example) can sometimes be the best solution.

How bright should kids’ bike lights be?

Brightness is measured in lumens. For younger children riding in well-lit areas, 20–50 lumens on the front and rear light is usually enough to be seen. For older kids cycling on darker roads, a front bike light of around 100–200 lumens is a safer choice, with a rear light of 20–100 lumens for visibility.

Some of the best bike lights for kids come with multiple brightness modes so you can adjust to the conditions.

Are rechargeable bike lights better than battery-powered ones?

Many parents prefer USB rechargeable bike lights because they’re easy to charge, more eco-friendly, and don’t require buying spare batteries. Simply plug them into a charger and they’re ready to go.

Can bike lights be used for other activities?

Yes! Some of the best kids bike lights double up as wearable lights which are also great for walking, scooting, or running in the dark.
