UK law requires your bike is fitted with a suitable rear light when cycling. Nasty knocks from behind can incur severe consequences, therefore protecting yourself from sleepy drivers with restricted visibility is paramount to your safety.
Bright LED rear bike lights can help mitigate the risks associated with cycling at night and alert drivers, pedestrians and fellow cyclists to your position on the road. Whether you commute to work, enjoy the thrill of country roads or prefer to race around parks with friends, you'll need to equip yourself with one that suits your needs. To help you decide, in this article we rank the top 10 rear bike lights in the UK, with handy links to buy them online on Amazon and eBay!
We dived into a sea of rear bike lights and rose to the surface grasping all the information you need to know. How bright is bright enough? Does the battery last long enough to handle your average journey? We'll answer these questions and much more below.
Bike light brightness is measured in lumens, or lm, which tells you the total visible light emitted. Your rear light acts a safety beacon, rather than an illumination tool to help you see, which means you require a high brightness.
while anything above 20 lm will be sufficient, many the latest products on the market produce far stronger beams, with 250 lumens being the most powerful on our list. If you're unsure which to pick, consider the time of day you usually ride. Brighter lights are better for ensuring you are seen during daylight hours, whereas a dimmer beam at night will stand out without hindering approaching drivers.
When you purchase your front light, there's a good chance the brand will throw in the rear light for free. While this approach works, there's every reason to buy the best product you can afford. By investing a little extra, you can reap the benefits of multiple functions to ensure you're prepared when the unexpected arises.
There are many reasons to choose a model with multiple lighting modes to cater to whichever situation you land in. Most rear lights will provide at least one steady and one flashing mode.
Flashing modes will help to preserve battery life, while the different speeds and brightness will alert drivers and help them judge your distance.
Some rear lights even come with special lighting features, such as ones capable of firing laser beams to create a virtual cycle lane!
If you're cycling into the night, down winding country lanes, there are few things more dangerous than your light failing prior to you running into a speeding car. Think about how long your average ride lasts before investing in a new rear light to ensure you're not put in a perilous position.
There's no set standard for battery life, although most will last between 6-10 hours, which easily outstays the average ride. For lengthier treks, you can find rear lights with extra long battery life, with some lasting over 60 hours.
We recommend choosing a bike light that's USB rechargeable. While you'll perhaps have to plug it in more often that you would with alkaline batteries, you will save money and get the peace of mind that you won't get left in the lurch one night with no spare batteries in sight.
Look out for different types of mounting systems to prevent wasting money on rear lights that you can't fix to your bike. For example, some tail light brackets require you to fix them using zip ties. This will ensure a tight, customisable fit. However, to remove it you'll need to snip off the ends, which may be an issue if you don't have scissors handy!
Smaller bike lights are often simple to mount using some form of rubber or silicone straps, rings or bands. These wrap around and fasten to your seat post, no matter the type of bike you have, and are easy to install, reliable and versatile. When you don't need the light to protect your behind, you can fasten them to your clothing, helmet or backpack.
Always remember, no matter the type of mounting, to remove your lights when you park your bike. This is because thieves actively hunt out those that are left attached.
Now you've equipped yourself with the information needed to choose the best rear bike light for you, it's time to rank our top 10 favourites to buy in the UK!
