The best front bike lights: Be seen day and night

See the route ahead and be seen with the best bikes for the front of your bike.

Bike riders with front bike lights on in the dark

Having lights on your bike isn't just about you being able to see where you are going. It's about other people being able to see you coming, too.

Like cars that run Daytime Running Lights to help with road presence and be seen, bike lights also deploy a similar technique. Front bike lights often come with different mode settings to help you be as visible as possible, as do rear lights.

But front lights shouldn't limit you to daytime riding only - the best bike lights will keep you riding well into the night with a bright beam. This will help you not only see where you're going but it will also help you see potholes and drains and other such dangers on the road.

What to look for in a front bike light?

This depends on the riding you do; if you do more commuting in the summer, you might want a front light which has a nice bright flash that can be seen by pedestrians and drivers alike. This would alert people to your presence and help you to be seen.

If your riding is predominantly at night or early morning in poor lighting conditions, having something bright will help you see where you're going and what's around you.

What is a lumen?

A lumen is a quantitive measure of light or brightness. The higher the lumens number, the brighter the light.

To put it into measurements of your home, a 40 Watt bulb is around 450 lumens, a 60 Watt bulb is about 800 lumens and a 75 Watt bulb is about 1,100 lumens.

The best front bike lights

Let's poke about into the well-populated world of bike lights and pick out a few that caught our eye.

Bookman Block Front Light
Price: £12.99 (starting)

www.wiggle.co.uk

This small, durable, and sleek little light won’t be the one which lights the whole road on your evening rides, as it can only put out 50-lumens at full power. However, it’ll be enough for daylight and low light conditions to help you be seen.

Rechargeable via USB, the Lithium ION battery can run for 25 hours when used in its lowest setting, blinking at 14 Lumens. When used at its max setting of 50 Lumens on a steady light, it’ll run for 1.5 hours.

Pros

  • Easy to mount to your bike
  • Compact enough to fit into your pocket
  • USB rechargeable

Cons

  • Not overly bright
  • Will need recharging daily if used on full power
Lumens: 50 max
Battery life: 25 hours max 1.5 min
Charge time: Two hours from flat
Charge method: USB

This small, easy-to-fit front light will help you be seen more, rather than guide you through the dark country lanes on a commute home. At only 15 lumens, it’s not exactly what you might call bright, but it is enough to get noticed.

It has five different light modes (three different kinds of flash, pulsing and solid). The light casing has an IPX7 water resistance rating, is incredibly lightweight at only 22 grams, and the wide optic lens provides more than 180 degrees of visibility.

Pros

  • Easy to fit
  • Compact design

Cons

  • Not that bright
Lumens: 15 max
Battery life: 22 hours max (variable on how it’s used)
Charge time: 2.5 hours from flat
Charge method: USB

Knog Plugger Front Light
Price: £31.89

What Kong has done here is make something that sits between a light which will get you seen and help you see in equal measure.

It's the ideal light for those dusky summer evening commutes home. It's very impressive to get 350 lumens in such a small and reasonably priced light, and it'll be enough to help you spot potholes and drains.

Pros

  • Easily attached
  • Lightweight (85g)

Cons

  • Consider durability at this price
Lumens: 350 max
Battery life: 180 hours on eco mode, 1.5 hours on max setting
Charge time: Five hours from flat

A light for city commuters who want to be seen, the Beryl Laserlight Core is a durable and compact light with waterproof construction and low weight.

At 400 lumens, the light also benefits from laser projection technology, which helps to improve your visibility at junctions and helps to keep you seen if you're in a blind spot. There are four different modes which give you a range of flashing and steady light options. The Day Flash cuts through distractions on busy roads and is superb in the daytime.

Pros

  • Bright light
  • Fully waterproof
  • Easy to mount

Cons

  • Could be brighter at this price point
Lumens: 400 max
Battery life: 4.5 – 41 hours
Charge time: 50% in one hour, 100% in 4.5 hours

The Trace Mk2 is a front bike light designed to help you be seen during the day. It’s small, compact, and has three different brightness levels with a maximum output of 125 Lumens.

In a neat little feature, this light has a traffic light system for letting you know how much battery life is left, so you don’t get caught out on your rides. It’s small and lightweight, making it perfect for commuting or those summer evening time trials.

Pros

  • Lightweight
  • Compact
  • Decent battery time

Cons

  • We would prefer more lumens at this price

Frequently Asked Questions

How bright does my front light need to be? There isn't a legal requirement to say you need your front lights to have a minimum amount of lumens. Our advice is always to buy what you can afford and how you will ride. Lights do not guarantee that everyone on the road will see you but generally speaking, the brighter the light can flash, the more chance you have of being seen.

Are bike lights a legal requirement? No, you do not have to have lights on your bike to ride in the dark; however, it is heavily recommended to see the road conditions, and people need to see you.

Do I need bike lights for commuting? Bike lights will help you be visible when commuting. Having a light to help you see is also important if you commute when it's dark. This will generally be a mode setting which is a steady light but also has a pulse to allow you to be seen.
