Best bike lights reviewed 2022
The best bike lights rated, including how much to pay, the features you need, and our pick of the best bike lights on the market


The best bike lights are essential if you're planning to ride after dark or before daybreak or even if you're out in poor conditions during the day.
Most cyclists will regularly ride after dark in autumn and winter, making bike lights an essential piece of kit, although daytime running bike lights are growing in popularity because they help you to be seen out on the road, even in bright sunlight.
We've split our guide into four categories: high-power front lights, mid-power front lights, rear lights and light sets.
Below that you’ll find all the details on our recent four-way grouptest, covering a selection of top-flight high-powered front lights. At the bottom of the page, we delve into all the techy details of what to look for in the best bike lights.

The Lezyne Macro Drive 1300XXL, as its name suggests, puts out 1300 lumens. It provides a wide beam and attaches to the handlebar via a rubber strap, which is thick and stretchy, resulting in a robust overall package when paired with the CNCed aluminium body.
You can choose to use the 'Race' mode, which lets you switch between 1300 lumens and 130 lumens, or the standard mode, where you can cycle through all seven options. The Race mode is handy as it effectively lets you 'dip' the beam.
Charging is via a micro USB cable. The battery life is a claimed 2.5 hours. We tested this twice, and found we still had either a flashing red light (indicating 5% battery left) or solid red light (indicating 5-10% left) after 2 hours 20 minutes.
All in, we concluded that this is a solid light which we would wholeheartedly recommend.

Exposure has been a market leader for some time and the Sussex based brand is known for engineering products that really last - members of the CW team have managed to keep some of Exposure's beams going for over a decade. So, whilst the price is high, if you've got the cash we'd fully recommend the Strada MK10.
The 1500 lumens is measured, not calculated - meaning that you really do get a full 1500 lumens. The beam was quite visibly the brightest of the bunch in our group test.
Battery life is 2 hours, and Exposure's digital screen actually displays the number of minutes you have left; these figures rang true for us.
Exposure also offers a full 20 modes, with a feature that allows you to select a 'sub mode' so you don't have to cycle through all 20.
The mount is a beautifully engineered aluminium construction, though it is fiddly to swap between bikes when compared with a simple rubber strap.

Knog's PWR Trail 1100 didn't perform as well, across the board, as the offerings from Lezyne and Exposure, but it still scored 4/5 and is a solid product.
The Knog light is a modular system; you can actually use it as a power pack, should you find you're riding in daylight but (for example) need to charge your phone. This is a great touch, however, its battery life is only 1.7hrs, and we did find that claim rang true - giving it the shortest burntime of all those on test.
Changing modes is performed via a twist function. This is very easy to use, and could be particularly useful when wearing gloves.
The mount is a clamp with a ratchet wheel; whilst a little more fiddly than a rubber strap, it is robust.

The Dayblazer 1500 from Blackburn is the lowest scorer on test. It lost marks for the mount, which broke during testing, largely due to its skinny profile and the amount of force required to fit it to a chunky road bike handlebar. In addition, whilst it claims to come with a helmet mount, we'd suggest it comes with a helmet mount adapter which doesn't provide all you'd need to fit the light to your lid.
On the plus side, the Blackburn Dayblazer 1500 does put out plenty of light, and it was the lightest option on test, at 143g. The body is robust, and water and grit protection is excellent.

The PR1600 is the second most powerful of a five light line-up. We liked its beam pattern that combined spread and spot illumination well for fast riding on unlit, potholed lanes, while its price for its output undercuts better known brands. As well as the light itself you get a wireless remote in the pack that makes it easy to dip the light for an oncoming vehicle without having to toggle through the multiple modes, of which there are eight total: five for road use and three for trails.
Battery life on the highest mode is 1.4 hours, which is OK if not amazing, but you do have a digital display built into the light telling you how much burn time is left - a marked improvement on the usual colour-changing LED.
There's a USB plug built in which, like the Knog PWR range, lets you power up other devices, but the Ravemen light doesn't provide any side-on visibility features, so it's not the best for commuters.

The Exposure Sirius Daybright packs a lot of light for a compact. lightweight package. Like Exposure's other lights, it's programmable so you can choose the light settings that work best for you. There's a bright central spot with plenty of peripheral illumination as well.
It's worth bearing in mind though that the standard rubber strap mount, although it functions perfectly on standard round handlebars, is too short to wrap around a wider aero bar top, so you may need to buy a second strap to daisy chain to it. If you add a helmet mount to your purchase, the Sirius is a great option for a lid light.

With two LEDs, there's a wide cast of light from the Micro Drive Pro, although we'd have liked a little more side illumination. The four constant modes give you lots of options, although you can cut that down to just two by selecting the Overdrive mode, making selection as you ride a bit easier.
The light has a green hue, that we found more comfortable to the eye than the bright white of many front lights. The hefty alloy light feels very robust and mounts easily to a range of bars with the attached rubber strap.

Like the other lights in the Knog PWR range, the PWR Rider has a built-in USB port so you can use it as a power bank to charge other devices. It's also programmable, so you can set as many modes and light levels as you want, if the six ready-programmed modes don't suit.
At 114g, the PWR Rider is not too heavy to use as a helmet light and it's easy to attach to the bars with its integrated rubber strap mount. There's a good, elliptical spread of light that lets you ride at a reasonable pace even on unlit roads.

Lezyne KTV Pro rear light uses a simple USB charging stick

A bright 75 lumen rear which offers a variety of modes, including a daytime option.
Charging is via an inbuilt USB adapter: you just whip the rubber bottom end off the light and plug it in. The light uses a rubber band for mounting and can fit aero or round seat posts, though we did find it suited aero versions better and was prone to twist on round posts so that it wasn't pointing straight behind.

Cateye Rapid X3 rear light mounts simply, with an elastic band

Plenty of modes and 150 lumens on the highest output make the Cateye Rapid X3 a very competent rear light. We like that it packs two sets of independently operated LEDs in the same body, which gives lots of output options. It automatically goes into a reduced 'low battery' mode when it's running out of juice, while charging takes about 3 hours.

At over £50/ $50, this is quite a pricey option - but it's got a unique party trick. The 250-lumen rear bike light also incorporates laser beams which can be displayed either side of the cyclist, designed to reduce the number of close passes cyclists experience. The mount is compatible with both round and aero seat posts, too.

Bontrager Flare RT rear bike light packs a punch in a small package

Don't be fooled by the Bontrager Flare RT's compact size, this miniature tail light backs the punch of a flashbang. The LED inside only outputs 90-lumens, but the optics built into the lens focus the beam in such a way that the Flare RT can be seen from up to 2km / 1.2mi away. ANT+ connectivity means it can be connected to Garmin computers to show battery status and for control, and an integrated ambient light sensor adjusts brightness for maximum visibility.

There's no doubt that you'll feel safer in the knowledge that you'll be much more likely to be seen by approaching cars and other traffic with the Exposure Blaze rear light attached to your bike. It truly is a dazzling light that cuts through the light pollution to grab the attention of other road users. The Daybright function is impressive in bright sunshine, especially at cutting through low level sunrays.

Garmin's Varia RTL515 has four light modes, 65-lumens under the hood, and has a viewing angle of up to 220-degrees, but that's not what sets this light apart.
Hidden inside this sleek looking taillight is a rear-facing radar which can pick up cars from up to 140m / 459ft away, and when connected to a Garmin or Wahoo head unit, alerts you to and tracks cars as they approach. It may sound like a gimmick, but in our experience, it is surprisingly accurate, and often picks up cars before our ears do.
