How to choose your bike lights & our top picks

Staying visible and safe should always be the priority when it comes to riding a bike, and one good way to do so is to ensure you have a good front bike light and rear bike light. Explore the options below and discover what’s best for you and your ride.

Between sunset and sunrise, having a functioning front and rear light is a legal requirement, but we'd recommend it at other times too, be that on bright days or when it's grey and rainy. Whether it's a light to purely be seen, or a light to see, on the road or off-road, here at Sigma Sports we stock a large range of bike lights from the likes of Exposure Lights, Knog and Lezyne, to name just a few, and have experts on hand to help you choose.

What do I need to consider when choosing a bike light?

Lumens

Lumens measure how much light a bike light puts out, so it's the quickest way to compare brightness between models before you factor in your specific ride.

Therefore lumens are a key detail, the number of lumens indicates the visible light light output from the front or rear unit, so how powerful it is. Rear bicycle lights normally go up to about 50, whereas front lights can be anything from 100 to 1000s of lumens, with an extremely bright option delivering a more powerful light for faster riding. Where you ride will determine what you need, so in built-up, well-lit areas you'll need far fewer lumens than in rural places or when heading off-road.

If you're wondering how many lumens to choose, around 100 to 300 can work on lit streets and lit roads, roughly 400 to 800 suits darker rural roads, and higher levels are better off-road.

Rechargeable bike lights: run time and charging

Rear lights generally have a very long run time and front lights can range from around 1.5 hours at higher outputs to well over 20 hours, with battery life varying by mode and some lights stretching as far as 107 hours in lower settings. A decent battery life depends on the type of ride you do, and lower modes will usually extend runtime significantly. The higher the output, the faster the battery will empty and so some lights will switch modes automatically to save power as it gets low, to get you back safely. As a practical example, a 4000mAh battery can last up to 23 hours on low output.

Most bike lights are rechargeable via USB, and you should look for enough battery life to easily cover a few days of commuting, so if necessary you can charge during the day or overnight. The charging port in the light is likely to be micro USB or USB-C, and if charge time is important, USB-C is the one to go for. Some brands such as Exposure have their own system and some plug directly into a USB port with no cable required. The Exposure Strada Mk12, for example, has a battery life of up to 36 hours.

Others make broader proprietary battery life claims or use a separate power pack for longer off-road runtime. The Lezyne Macro Drive 1400+ offers 1400 lumens and around 3 hours of runtime, and some larger units can also double as a power bank.

A small number of compact rear lights still run on replaceable coin-cell or AAA batteries, which can be a useful lightweight backup even if your main lights are rechargeable.

Bike Light Modes

Choose a bike light with at least a few different light modes, with flashing modes for being seen and a constant mode or constant light for a steadier beam in lower light. If you plan to use it during daylight, many are available with specific daytime lights or a daytime pulse mode that emits more lumens than the light's maximum steady output, cutting through distractions particularly well. In practice, flashing modes are usually best for daytime visibility and can extend battery life significantly, while constant mode is better when you need a steady beam to see by.

Front and rear lights: what’s the difference

A front light and a rear light do different jobs, so it's worth thinking about them separately rather than as a single purchase. Front lights show white and range from low-output "be seen" beams to powerful spots designed to light up the road or trail ahead, while front bicycle lights are built to help you see and rear lights focus on making you visible from farther back and from wider angles, which is why the lumen range is so wide.

Shop front bike lights

Rear lights show red, prioritise visibility over brightness, and typically top out at around 50 lumens with a wider spread so you're seen from behind in traffic; that wide-angle visibility helps drivers pick you out more easily and is a real advantage for night riding.

Shop rear bike lights

Most riders are best served buying the two separately, so each can be matched to the job it's actually doing, though some of the best rear bike lights and complete bike light sets can still make sense once you know what you need. At minimum, riding after dark in the UK means a white front light and a red rear light.

Other features to look out for

  • Most lights have a waterproof casing for reliability, and for general riding it’s worth looking for at least IPX4, while mountain use or harsher wet conditions are better served by IPX6; in practice, higher ratings relate to protection from a low pressure water stream or even a high pressure water stream. Those designed for off-road use are built to be more rugged and resistant to potential knocks, and modern bike lights also vary in beam shape, legal fit, and overall light functionality.
  • Useful premium extras include smart features such as auto-dimming, app control, GPS pairing, and support for GPS devices, with some models including Lezyne StVZO lights-style beam control for road use.
  • A smart light may support a handlebar remote, while a smart bike light can use an ambient light sensor to adjust output automatically.
  • For riders who prioritise continuous power over charging routines, dynamo lights remain a practical alternative.

Bike lights for commuting

The freedom to choose your route, escape the rat race and keep fit on the way to work - commuting by bike is great, although it does come with its challenges. Safety is always a major concern, especially when riding during peak times and in built-up areas. With a lot of distractions on the road, standing out from the noise is of paramount importance to help reduce the chances of a collision. Bike lights play a crucial role when it comes to increasing your visibility.

In brightly lit and urban areas, the priority is being seen by other road users, as you don't need huge amounts of lumens to see where you're going. Aiming for 100-200 lumens and a wide beam is sensible, and some lights have side cutouts so you can be spotted from more angles of approach. For city riding, daytime lights with wide-angle optics and strong daytime visibility are a smart choice in traffic. If you want extra awareness, smart rear-light options such as the Garmin Varia, which adjusts light intensity based on vehicle proximity, and the See.Sense Icon, which alerts users of approaching vehicles, are worth considering.

Rural cycling bike lights - to see

Don't let the shorter days stop you riding and training outdoors. Whether you're on a road bike heading out on an unlit club run or covering rural lanes and trails, a good set of bike lights can illuminate the road ahead and ensure your trajectory is clear of potholes and other obstacles. The best front bike light for rural riding is not just about peak output, but also beam quality and a controlled light beam that lets you read the road ahead. We have taken a closer look at a number of lights, powerful enough to ensure even the darkest of roads or trails are navigable.

Ensure you have 400 lumens as a minimum, although we would recommend more, as the more lumens, the more detail you will be able to pick out in front of you. Look for long run times, as the brighter the light, the more power is used. Road cyclists covering distance after dark should also prioritise a light with a steady, focused daytime pulse mode, with constant mode for seeing and flashing modes for being seen, useful at a distance in traffic as well as on unlit country roads.

Bike lights for riding off-road

Riding off-road at night can be a thrilling experience, and if you're lucky enough to have a commute route that takes you into woods and onto trails, a decent light will improve visibility for more control, more speed and more fun. Unlike general commuter options, dedicated mountain bike lights are built for technical terrain and night riding where speed, rough surfaces and changing lines demand more from your setup. As with the best mountain bike lights, look for 1500 lumens or more; some models emit over 4000, and can be as bright as car headlights on their strongest modes. Run times will be limited at these higher outputs, but should give you at least an hour before you need to switch modes.

Think about how bar lights differ from a helmet light, as a bar mounted light gives you the broad trail illumination needed to read the ground ahead while helmet mounted lights show exactly where you are looking through corners and over obstacles. Most off-road systems let you mount lights to the handlebar or use a helmet with a secure helmet mount, and some setups also work with an out front computer mount or a remote-compatible head unit for cleaner integration. Beam shape matters off-road just as much as beam pattern, especially when pairing a bar mounted light with a helmet light. All the lights tested for this kind of riding should have strong waterproofing, secure fixing points and enough runtime at full power for genuine trail use.

What type of bike lights are best for me?

Your commute will very much determine what you need. In cities and lit-up streets, you’ll get away with something smaller, but on rural lanes and off-road, being able to see exactly where you are going is vital. If you’re unsure how much power you need, or if your commute will be in a mix of different areas, remember that most lights have a number of different modes and will offer lower lumen options so get the light best suited to the darkest areas of your ride.

Maximise safety out on roads and trails by picking a suitable front and rear bike light. We’ve picked a few more options here:

Bike Light FAQs

Do I need lights during the day?

Not legally, but it's still a good idea. Distinct daytime running modes are one of the most effective ways to be seen in busy traffic, and many riders now treat them as standard on every ride, not just after dark. They matter because strong flash patterns improve daytime visibility when ambient light makes riders easier to miss.

What lights do I legally need?

A white front light and a red rear light, both fixed to the bike itself rather than to a helmet or clothing. You also need a red rear reflector, and bikes made since October 1985 need amber pedal reflectors too. These are the minimum requirements for UK cycling during dark hours.

Are flashing bike lights legal?

Yes. Flashing front and rear lights are legal on their own, provided they flash at between 60 and 240 times a minute, which covers the vast majority of lights sold today. A constant light setting is also commonly used to meet legal and practical visibility needs.
