Longer nights and poor visibility conditions shouldn't present any obstacle to riding your bike. If you're like us, you'll want to ride all year round; the good news is, with good kit, and a good set of cycle lights, you can!
We've segmented down the range of bicycle lights available at Wiggle into three categories: Urban/Commuting, Road and Off-Road. In this guide we take a look at the differences, and what to look for...
Output: What are lumens?
In simple terms, lumens are the unit of how bright a light is, to the human eye.
Batteries: What are my options?
You can still buy cycle lights that run on disposable alkaline batteries; but most lights now feature built-in rechargeable batteries.
The most common rechargeable batteries are Lithium Ion (Li-Ion) or Lithium Polymer (Li-Po); these are smaller, lighter and more powerful than disposable alkaline batteries, making them perfect for bike lights.
Most rechargeable cycle lights charge via USB, and some lights even feature a built in USB connector - so you don't need a cable to charge them at all.
More powerful front lights take a long time to charge via USB, so some come with the additional option of a mains charger.
More and more rechargeable lights are fitted with battery life indicators now; so you know exactly how much juice you have left. Some lights have a small LED indicators, which change in colour to indicate how much power is remaining.
Light mounts: How do they work?
Most rear lights and safety lights use a strap or band mounting mechanism; which you can easily wrap around your seatpost or handlebar, often without the need for tools. Because these kind of mounts are easy and quick to remove, they are ideal for commuting bike lights.
On higher powered front lights, which are typically heavier, we tend to see clamp mounts. These are more secure, so can cope with rough terrain and repeated use. Most clamp mounts feature some means of quick-release for the light unit, so you can still remove the light with ease.
What are the best lights for you?
The type of bicycle light that you choose, will depend on the kind of riding you do, as well as the kind of conditions you ride in. See which of the below categories best describes your riding.
Bike lights for commuting and urban use
If you're riding in a built-up area, and the road or path is well lit, then your main priority should be to make sure you're visible to other road users. These are your 'Be Seen' Safety Lights.
Safety lights will usually have at least one constant lighting mode, in addition to multiple flashing modes. They also offer higher levels of side visibility; so you can be seen at junctions by pedestrians and other road users.
We've all seen the guy who looks like he's run off with the lighting rig from Dave's Mobile Disco; with multiple flashing lights, all over his bike, bag, clothing and helmet. Well, you may think it's a bit overkill, but remember you did see him! Fitting more than one light with a combination of flashing modes will always make you more visible.
The Lezyne Zecto Drive Light Set is the perfect bike light set, for when you want to be seen on the road.
The more adventurous commuter
If your commute takes in some unlit roads or paths, then you'll want a more powerful front light; so you can 'see' as well as 'be seen'.
Anything over 200 lumens will be able to cast a beam on the road, and offer sufficient light to ride on unlit roads and paths, at a sensible speed.
If the terrain is likely to be rough, or you are likely to come across hazards in the road, then you may want something brighter.
The LifeLine 375 Lumen Front Light is the perfect option if your commute takes you on a few unlit roads or paths.
Bike lights for serious road riding
When your riding (or "training") takes you on unlit roads, at a fast pace, then you need to think about seriously upgrading your Lumen output.
A powerful front light is vital to illuminate the way ahead; picking out potholes, rouge badgers and stray pedestrians!
For this category, we're talking about powerful, bar mounted front lights - ideally with an output upwards of 600 lumens.
The right selection of lighting modes is also important; allowing you to adjust your light output to your surroundings, and manage your power reserves on longer rides.
The Exposure Strada 1200 Road Specific including Remote Switch is designed specifically for the road.
Back-up and safety lights for serious road riding
High powered front lights designed for road riding, tend to have quite a concentrated beam; so you can see where you're going, but not dazzle oncoming drivers. The downside of this is that they can be less visible from the side. To improve your side-on visibility, consider fitting an additional road cycling safety light to the front of your bike; in flashing mode it will provide you with extra presence on the road; whilst it can also be a useful back-up light if you main light runs out of battery.
Adding the Lezyne Strip Drive Front Light to the front of your bike, will help make you more visible to other road users.
On the rear, a bright safety light will allow other road users to see you from a good distance. Similar to commuting lights, using the flashing mode, and doubling up on these lights, will make you even more visible.
Many high-end rear safety lights are now compatible with 'enthusiast road cycles' that have aero seatposts; they do this with longer and more flexible band mounts.
Bicycle lights for off-road riding
Riding a bike off-road, at night, offers a whole new dimension to your experience! Those familiar trails will feel like adrenaline-inspiring new routes, as they look a whole lot different under the cover of darkness.
You're going to want a good front light for your night time off-road riding though; because otherwise those rabbit holes and overhanging branches will be like land-mines and trip-snares in the dark.
So what kind of light do you need for off-road bike rides? Well, the first thing we'll say, is don't use your commuting lights! They might seem really bright, even on unlit paths, but out in the wild you need some serious illumination!
As a bare minimum, you want a powerful bar mounted front light, ideally with an output upwards of 1000 lumens. These off-road specific lights will have a wider beam pattern too, so they can illuminate the whole of the trail in front of you.
High powered off-road lights feature the ability to "toggle" down the light level; so you can light up the world on those technical descents, but reign back the power, and conserve battery life, on those long uphill drags.
A heads-up on the benefits of helmet lights for off-road riding
In addition to a bar mounted light, a helmet mounted light with a narrower beam will help you to see round corners, and spot any additional hazards that might be lost in the shadow of your main light.
The Exposure Diablo Mk8 with Helmet and HB mount is the standard to which all helmet lights are compared, and offers outstanding performance.
Summary and buying advice
Bike lights have developed phenomenally in the last few years, and the technology we now have means there is no excuse for not being able to see, or be seen, at night-time.
Whilst we've categorised the bicycle lights in this guide into three categories, there are many that will serve you well for all kinds of disciplines and uses; and with additional mounts available, you can easily switch your lights between bikes.
We'd always recommend that you purchase a light that will give you a bit more battery life than your typical ride length; that way you've got a bit in reserve, should you make an unexpected detour, or need to stop for a mechanical problem. If you are looking to do long night rides it may be worth purchasing additional batteries to carry with you.
Final recommendation? We'll leave you with one of our favourite lights on the market at the moment... the great all-rounder, and very well priced Lezyne Power Drive 1100XL Front Light.
