The Best Bike Lights of 2025

On the road, bike lights are critical for our safety. Whether you need to see, be seen, or both, the best bike lights of today have come a long way from the lights of yesteryear.

There are so many bike lights on the market these days that choosing the right ones can be downright frustrating. With front and rear lights, lumens, beam patterns, light modes, and more, understanding exactly what you need is a challenge in itself.

To help, we rounded up our favorite bike lights and tested them for months. Our expert testers took evening grocery runs and early morning commutes and spent plenty of time riding dark bike paths, country lanes, and gravel roads to assess each model’s performance.

Below are our favorite bike lights for road, gravel, and commuting. If you’re a mountain biker, we have a full guide to the best mountain bike lights that will help you navigate singletrack long after sunset.

Editor’s note: This guide was updated on January 21, 2025, with the addition of the top-rated Knog Blinder 900, the impressive Outbound Lighting Detour, and the budget-friendly NiteRider Vmax+ 150.

How We Tested Bike Lights

Our expert testing team is composed of experienced cyclists and outdoors-oriented people looking for the best products on the market. Our staff includes former bike racers, recreational cyclists, folks who bike-commute 60 miles a week, and everyone in between — people who care about fit, finish, and function in every product we use.

We take two approaches to our hands-on testing of bike lights. First, we take a look at the manufacturer’s specs and see if they hold up to real-life use, running down the batteries at different power levels and recharging them (when applicable). Then, we mount each light to our bikes and pedal off into the dark, looking at beam distance and how difficult (or easy) it is to change lighting modes and settings. Needless to say, the brightest light isn’t necessarily the best.

Lead tester Paul Mandell has two decades of experience in the saddle as a competitive racer and recreational rider. He completed his master’s degree in exercise science, where he studied the critical power model for cycling. These days, he prefers lift-accessed gravity riding and long adventure rides with plenty of descending. He still finds time to get out for the occasional gravel grind or single-track loop near his home base in California’s Eastern Sierra.

Additional testing was done by GearJunkie Editors Seiji Ishii and Jeremy Benson. Ishii has been cycling for the past four decades and has seen the evolution of bike lights in that time. From the clunky, big, and heavy lights of yesteryear to the advanced, compact, lightweight, and bright lights of today, he’s tried them all. A resident of Texas, Ishii often uses lights while riding after sunset to beat the summer heat.

Benson has been professionally testing bikes and related accessories for the past 8 years. He spends lots of time riding bikes for product testing, training, and fun, and would rather finish a ride in the dark than spend another day on the indoor trainer. He’s used dozens of bike lights over the years and has an appreciation for modern lights that he can easily carry with him and pull out when the sun goes down, and he’s still miles from home.

Buyer’s Guide: How to Choose a Bike Light

Every cyclist should have a set of reliable bike lights. When choosing the ideal lights to fit your needs, the sheer number of options on the market can feel confusing and difficult to navigate. From front and rear lights to lumens and side visibility, there are numerous factors that must be considered when selecting bike lights.

In this buyer’s guide, we’ll break down each of these factors and hopefully simplify your selection process. You’ll be cruising down well-lit roads, paths, and trails in no time.

Brightness and Lumens

Just about every bike light on the market comes with a rating in lumens. Lumens are a unit of brightness. Simply put, the higher the lumens, the greater the brightness. However, while the lumen count is a good place to start when thinking about brightness, it doesn’t tell the whole story.

Ultimately, the brightness of a bike light is a product of the lumen count, beam width, and beam angle. A light with a super-high lumen count is great, but only if it has been designed to use its brightness effectively.

Because every cyclist has different needs, there is no fixed lumen count that every shopper should aim for. If you are riding in the daytime and simply want to increase your visibility and be seen by other road users, 100+ lumen front and rear lights should be sufficient.

If you are riding in urban environments in the dark and need enough light to see where you are going, you’ll want a front bike light with at least 400 lumens. If you plan to ride on roads or bike paths in the dark with no artificial lighting, we recommend a front bike light with at least 600 lumens. While brightness is good, some lights can also be too bright and may wash out finer details in some situations.

Front bike lights are brighter than rear bike lights because they must illuminate the road ahead. Rear lights are meant to help you stand out from other people on the road or trail and generally emit red light.

It is important to note that most bike lights are not able to sustain their highest brightness setting for more than an hour or two. If you purchase a light that boasts 1,000 lumens, just know that the light will not be able to remain on that setting indefinitely. For example, the brightest light in our test group, the NiteRider Lumina 1800 Dual Beam, puts out a staggering 1,800 lumens, but the battery only lasts for 45 minutes at this setting.

It is important to note that most lights have multiple brightness settings. For example, the Lumina 1800 mentioned above has 4 levels of brightness: Boost (1,800 lumens), High (1,500 lumens), Medium (700 lumens), and Low (350 lumens). Riders have the ability to choose the setting that best suits their needs. Battery life corresponds directly to the level of brightness, and lights will run much longer on lower settings.

Front Lights vs. Rear Lights

While front lights need to be bright enough to light up the world in front of you, rear lights are mostly a safety mechanism that improves your ability to be seen. Most front lights are significantly brighter than their red-light-emitting rear counterparts. Front lights typically mount to the handlebars or front stem, while rear lights mount to the seat post or rear frame.

For road riding or commuting, we recommend picking up both a front and a rear light. Also, consider what you need the lights for. If you are only trying to make yourself more visible in the daytime, then you may not need the brightest front light. If you need to see in the dark, then you’ll want to consider some of the brighter front light options. Simply put, your needs may vary based on your riding preferences.

We’ve mostly outlined our favorite front and rear lights based on their own merit, but most of the front lights are also sold as bundles with a rear light. On this list, the Cygolite Streak Front and Rear Set is a great, affordable set of bike lights.

Bike Lights for Different Kinds of Riding

Road Riding and Commuting

Road riding generally involves straight lines and few obstacles. Riding on the road, whether for commuting, training, or just for fun, also involves interacting with traffic. Aside from lighting the way in front of you while riding in poor lighting, one of the primary purposes of bike lights is to be seen — even in the daytime. For this reason, we recommend front and rear lights so motorists approaching from the front and behind can see you.

For this kind of riding, we recommend a handlebar-mounted front bike light with a more focused beam that directs the majority of its brightness straight ahead. At the same time, it’s nice to have some light in the periphery to see potential hazards as you ride. The best front lights have a balanced beam that casts light a long distance and spreads a bit of light to the sides. We also look for daytime flash modes to make us more visible in broad daylight.

Rear lights are typically a bit simpler and they don’t need to be nearly as bright as front lights to make you visible. Rear lights are almost always red and will typically have both steady and flashing light modes. The seatpost is the usual clamping location, although some rear lights can be attached to clothing or bags, too. On this list, the Garmin Varia is an excellent road-riding light that makes you visible to motorists and has a radar function that can show you approaching vehicles on your Garmin computer.

Mountain Biking

Mountain bikers need to be able to see obstacles long before they reach them. Unlike most road cycling, mountain biking involves sharp turns and lots of major obstacles. Generally speaking, it helps to have brighter lights when riding on trails, and it is beneficial to have lights on both your handlebar and your helmet. Unless you are riding on roads to and from the trails, most mountain bikers don’t use rear lights.

Side Visibility

Side visibility can be an important factor to consider, and some lights rate higher in this category than others. When riding through busy streets, improved side visibility can help prevent accidents before they happen.

Most lights, both front and rear, intended for road riding or commuting have been designed to provide some level of side illumination. Often, these are small windows on the side of the light housing that emit a small but noticeable amount of light. In other cases, the lens of the light may be curved to be visible across a wider viewing angle. Regardless of how its achieved, it is a feature we appreciate and look for in bike lights.

Light Modes

The best bike lights have multiple light modes to suit varying needs and preferences. This often includes several steady modes with different levels of brightness, as well as a few flashing modes. The steady modes work best for lighting the way ahead of you so you can see where you are going in low light or darkness. Typically the different levels are fixed at intervals chosen by the manufacturer but provide a range of brightness for different situations.

Flashing modes are great because the intermittent flashes of light are attention-grabbing and may make you more visible to motorists than a steady light. These are most useful in the daytime for being seen, and the best front and rear lights usually have a few different flash or pulse modes.

Additionally, some lights have a steady pulse or steady flash mode where the light is on steadily and is accompanied by a flash or pulse. In low light or darkness, the steady flash allows you to see while also having the benefit of the attention-grabbing flash.

Battery Life and Burn Time

Battery life depends on many factors, including the size and type of battery, the type of LEDs in the light, brightness, and the light’s settings/modes.

Most rechargeable bike lights come with multiple settings. The highest and brightest setting will deplete the battery the fastest and vice versa. Good visibility is important, but you should always try to avoid unnecessarily bright settings in order to prolong your light’s burn time — especially on longer rides. You don’t always need to use the brightest mode on a light for it to be effective.

Flashing pulse settings tend to use less light than a steady beam, and they are great for being seen in the daytime. It depends on the light in question but, often, the flash settings can double or quadruple the run times.

When determining which light will work best for your needs, it’s incredibly know how you’ll be using it. Do you need a light to last for three hours on its highest output mode for nighttime training rides? Do you need an emergency light to carry with you in case you mistimed your route and the sunset? Or do you need some flashing lights to last all day on a century group ride? Knowing your lighting needs should help you narrow down the choice to find a light with a run time to match.

Mounting

Mounting front and rear bike lights is typically a relatively simple process. All of the lights we tested come with at least one mounting system and few provide multiple options. Generally speaking, front lights mount to the handlebar while rear lights mount to the seatpost.

While many mounting systems are self-explanatory, we recommend that users always read the manufacturer’s instructions for mounting. The majority of mounts are relatively universal in terms of fit and will work with a range of handlebar and seatpost diameters and shapes. This is not always the case, so it is worth checking the specs to make sure.

Depending on the surfaces and terrain you ride on, the stability of your bike lights may be a concern. If you ride rough gravel roads or particularly bumpy pavement, some lights can be prone to shifting. If that sounds like you, then a more secure clamp-style mount may be preferred over a stretchy rubber attachment. Similarly, some brands have mount options for GoPro-style attachments that can work with computer mounts or on bike helmets.

We especially appreciate lights that are easy to mount and dismount. When locking up your bike in a public place, you’ll want to be able to easily and temporarily remove your lights to prevent theft. The Cygolite Dash Pro 600 and the Lezyne Lite Drive 1000XL are among the easiest lights we tested to mount and dismount.

Price & Value

Bike lights vary wildly in price. Like most things, you generally get what you pay for. While it isn’t necessary to buy the most expensive light out there, we do recommend that you go for the nicest lights that you can afford. When you’re riding home in the dark, you’ll appreciate having a reliable light with plenty of battery life to keep you rolling along safely.

Budget

There are lots of super cheap, off-brand bike lights on the market. You could buy a front light off Amazon for $20, which might work but will probably make some major sacrifices in terms of brightness, mounting, battery life, and build quality. While these will usually do okay in a pinch, we always recommend going with an established bike light brand.

The Cygolite Dash Pro 600 is our favorite value option, boasting solid performance with its 600 lumens, multiple light modes, and $65 price tag. Similarly, the Cygolite Streak Front and Rear Set ($62) is a solid value for a combo that will cover most people’s needs.

Rear lights are generally much less complicated, less bright, and, therefore, less expensive than front lights. Even the least expensive options, like the Lezyne Femto USB-C ($20), are rechargeable, bright enough, and easy to use.

Mid-Tier

As you go up in price, even just slightly, front lights are brighter, fit and finish improve, and the overall quality is higher. In fact, two of our favorite front lights fall at the low end of the mid-tier price range. Our top overall pick, the Knog Blinder 900 ($80), earned its spot for its robust build, compact form, ease of use, and 900-lumen max output which make it a solid choice for a huge range of riders.

Similarly, the Fenix BC26R ($89) is a killer bike light made by a respected flashlight brand. At 1,600 lumens, it might be overkill for a lot of riders, but it boasts impressive run times, a nice form factor, a sturdy mount, and you can even swap batteries should the need arise. We’re surprised this light doesn’t cost more.

For rear lights, we like the NiteRider Vmax+ 150 ($35). Its max output of 150 lumens is probably overkill for a rear light, but it has multiple steady and flash modes, a long battery life, easy operation, and ensure that you’re seen by motorists coming from behind.

Premium

As prices climb up into premium territory, that often correlates to an increase in brightness and/or more advanced features. The NiteRider Lumina 1800 ($170) is a perfect example. With a max output of 1800 lumens, it commands a bit more than double the price of the Lumina 900 ($75).

The 1800 has dual beams with two LEDs, two lenses (distance and spread), and a larger battery. It might be overkill for most road riding, but it would be a great do-it-all light for those who mix it up on the mountain bike as well.

The Outbound Lighting Detour ($185) also commands a premium price along with the premium lighting performance to match. At 1200 lumens, it’s not the outright brightest, but it is well designed and its beam pattern, horizontal cutoff, sturdy handlebar mount, and unique Adaptive lighting mode make it one of the best lights that we’ve tried for serious riding after dark.

For rear lights, it’s a very large jump in price up to the advanced features of the Garmin Varia RTL515 ($200). This light dutifully serves the primary function of making the rider visible to motorists. It also works as a radar and connects to Garmin cycling computers or smartphones to provide the rider with alerts about nearby vehicles. This can help you be more aware of your surroundings, but the technology will cost you.
