Right Kind of MTB lights

When it comes to mountain biking on singletrack trails, the focus is often on the front lights that guide our way through the darkness. We’ve all experienced the thrill of night rides, feeling the adrenaline rush as we conquer rugged terrain under the moon’s glow. While riding with your friends, front lights help you stay connected and navigate the trails together. But there’s an aspect of mountain biking that we sometimes overlook—the rear lights.

In the world of mountain biking, rear lights may not be deemed essential when tackling singletrack trails, but they play a vital role in certain situations. You see, rear lights are a must-have when you find yourself riding in traffic, ensuring that other vehicles can spot you from a distance. They come to the rescue when you’re pedaling your way back home after a late-night adventure, making you visible on the road. These simple yet effective rear lights are not as powerful as front lights, making them budget-friendly with extended battery life.

Now, let me introduce you to the heart of nighttime mountain biking—innovative lighting solutions designed to enhance your experience. Whether you’re commuting to work or conquering challenging trails, modern bike lights are here to shed light on your journey. Imagine a headlight that’s easy to install on your bike frame, casting a broad and powerful beam of light that illuminates the entire path before you. The front bike light should ideally be positioned less than 150 cm above the ground, close to the reflectors, ensuring optimal visibility.

In the realm of bike lights, you have a choice to make—LEDs or halogens. LEDs may come with a slightly higher price tag, but they offer longevity and energy efficiency. On the other hand, halogen lights are more budget-friendly but require more power and have a shorter lifespan.

So, whether you’re riding to work, exploring the trails, or simply venturing out into the night, the type of mountain bike light you choose can significantly impact your experience. It’s not just about illumination; it’s about enhancing safety and fun in the dark.

Battery Runtime

One crucial factor to consider is battery life, and that’s where milliampere hours (mAh) come into play. This metric helps quantify a battery’s energy capacity, and it directly influences how long your lights will stay on. In my experience, a higher mAh rating is your ticket to extended rides without the worry of your lights fading into darkness.

For everyday trail riding, a battery life of 4-6 hours typically suffices. However, when you’re venturing into more remote areas or planning for a lengthy nighttime marathon, you’ll need a light with a longer-lasting battery. It’s all about ensuring that your adventure isn’t cut short by dwindling light. That’s why choosing a mountain bike light with a high mAh rating is essential.

Moreover, the best models often offer the convenience of USB recharging, adding a practical edge to your gear. But with the market brimming with various options and varying mAh ratings, finding the right battery for your needs can be a bit of a quest.

For longer trail rides or extensive night cycling, opting for a high-capacity battery can be a game-changer. It keeps your path well-illuminated and your ride worry-free. However, there’s a trade-off between capacity, size, and weight. Larger batteries offer extended performance but might be less suitable for lengthy trips due to their bulk. Many riders, myself included, strike a balance by using medium-capacity batteries. These provide sufficient light for most riding scenarios and can be swapped out when extra light is needed.

In the world of mountain biking, your choice of battery runtime is a personal decision, balancing the need for illumination with practicality.

Lumens & Beam Pattern

When it comes to selecting lights for your mountain bike, one of the first things you’ll encounter is the term “lumens.” It’s essentially a measure of how much light a source emits. More lumens translate to greater brightness, and in my experience, this is paramount.

For those darker, less lit routes, I strongly recommend lights with at least 500 lumens. After all, it’s all about seeing the path ahead clearly. Now, while lumens are crucial, they don’t tell the whole story. Mountain bike lights take a beating from the trails’ bumps and jolts, so durability is key. Look for lights with rugged housings and strong vibration ratings to ensure they can endure the ride.

Then there’s the matter of the beam pattern. This refers to how the light is dispersed. A well-designed beam pattern produces a broad, even field of light that covers the entire path in front of you. Why does this matter? Two reasons: it helps you spot obstacles in your way, enabling you to avoid them, and it prevents you from blinding fellow hikers or bikers sharing your route.

In the world of mountain biking, the right beam pattern depends on your riding style and environment. For trail riding, a wider beam works wonders, while racers might prefer a narrower focus. Some lights even offer adjustable beam patterns, a handy feature when transitioning between different terrains. Lights that combine spot and flood outputs can be particularly versatile, offering the best of both worlds.

Now, when it comes to brightness, more is often better, especially when you’re racing through dense, dark forests. Speed and lumen output are directly connected because the faster you go, the more lumens you need to see obstacles coming at you. But, keep in mind, as lumens increase, so does the price tag. On this list, you’ll find lights with varying lumen levels, some exceeding 1,000 lumens, while others offer less power.

Water Resistance

I know firsthand that water and electronics aren’t the best of pals. It’s a simple reality. But here’s the good news—most manufacturers of mountain bike lights understand this too and have taken significant steps to make their lights resistant to water.

Some have even gone the extra mile to earn an official IPXX (International Protection) designation. This rating consists of two numbers. The first number, ranging from 0 to 6, represents the level of dust resistance (0 being the lowest, 6 the highest). The second number, ranging from 0 to 9, signifies the level of waterproofing (0 being the lowest, 9 the highest). So, if you’re particular about the conditions you’ll be riding in and you want peace of mind, opt for a light with the highest rating.

Most mountain bike lights available today are built to withstand exposure to moisture, although they aren’t meant to be submerged. They can handle some rain or wet trail conditions without a hitch. One of the primary benefits of a water-resistant light is its ability to shield electrical components from damage. Moisture exposure can lead to corrosion and other issues that may impact a light’s functionality. By encapsulating these vital parts in a waterproof housing, you can extend the life of your light significantly.

Whether you’re braving the elements in rainy weather or merely seeking the reassurance that your light can handle a bit of dampness, a water-resistant mountain bike light is a wise investment. It ensures that your biking adventures won’t be cut short by unexpected rain showers or wet terrain, providing both peace of mind and extended functionality for your valuable gear.

While these lights have a lot going for them, there are a couple of downsides. One issue I encountered was the USB charging cable. It’s disappointingly short, which can be a bit inconvenient, especially if your charging setup isn’t close to your bike storage.

Additionally, there were reports of a recurring problem with the on-off button. Some users experienced issues with the button, particularly when trying to activate the flashing mode. This could be a concern for those who rely on different lighting modes during their rides.

While these lights have a lot to offer, they do have a minor downside. The rubber straps used for attachment may be too short for oversized handlebars. It’s a small issue, but if you have non-standard handlebars, you might need to get a bit creative with the attachment.

I recently took the Cygolite Metro Mountain Bike Headlight for a spin in the UK, and here’s what I discovered during my testing.

The most prominent feature of the Cygolite Metro is its exceptional brightness. Even without having it mounted on my bike yet, I could tell that it’s incredibly bright. It casts a wide arc of light, making it ideal for lighting up the road or path in front of you, rather than just making you visible to others. This is exactly what I’ve been searching for, and the Cygolite Metro does it remarkably well.

Another remarkable aspect of this headlight is its versatility.

The Magicshine ALLTY 1000 with an effective cost is a sufficiently powered value, yet compact bike light.

I recently put the Magicshine Best Budget Bike Front Bike Lights to the test in the UK, and here’s what I discovered during my trials.

One of the standout features of the Magicshine budget bike front light is its ability to throw out a fantastic beam of light. Although it may be a bit more expensive than some other options, it certainly lives up to the adage that you get what you pay for. This lightweight and portable bike light truly shines when navigating unlit rural roads. If you’re looking for a light that provides outstanding visibility on those dark, winding paths, I would highly recommend this one.

Whether you’re using it for your daily commute or embarking on extended cycling adventures, it offers the performance you need.

While the Magicshine light has much to commend, it’s not without its flaws. Some users reported issues with the base of the light that attaches to the Garmin mount. In some instances, this component failed, posing a risk, particularly when it fell off while cycling. Strengthening the base mount could prevent such incidents and enhance the overall reliability of this otherwise fantastic light.

Another notable feature is the impressive range of this bike light. It effectively lights up the road or trail ahead, providing a clear line of sight. Whether you’re a road cyclist or a mountain biker, this light’s range is sure to meet your needs.

While the TOWILD CL1200PRO has numerous strengths, there are a few shortcomings to consider. One notable drawback is the absence of mounting hardware in the package. This means you’ll need to purchase the necessary mounting equipment separately, which can be an inconvenience.

A few consumers have voiced concerns about the mounting method, citing its weakness and lack of security. This aspect could be improved to ensure a more reliable and sturdy attachment to your bike.

One of the most striking features of these lights is their exceptional brightness. They are more than capable of illuminating even the darkest forest trails, providing ample visibility for night rides. Additionally, the presence of two light modes proves highly convenient. The first mode is ideal for trail riding, offering a strong beam to light your path, while the second mode is perfect for urban environments where there’s already sufficient lighting. This versatility ensures that these lights are adaptable to various riding conditions.

The battery life of these lights is impressive. I found that they perform well and can last for extended periods, making them suitable for long rides. The reliability of their battery life is a significant plus, as it’s essential to have a consistent source of light during nighttime cycling.

While these lights have many commendable features, there are some shortcomings that potential buyers should be aware of. Some users reported issues with the clip that secures the light, specifically that it can be prone to breaking. It’s important to note that these incidents occurred without any apparent misuse or accidents; the clip simply failed during regular use. The durability of this component could be improved to ensure the lights remain securely in place during rides.

Another area that requires attention is the bracket’s design. Some users found the supplied bracket to be inadequate for holding the light in place, even on smooth tarmac. This issue necessitated the use of modified or alternative brackets. While this doesn’t affect the light’s performance directly, an improved bracket design would enhance the overall user experience.

I recently had the opportunity to put the Best Budget MTB Lights to the test in the UK. Here are my findings regarding their praises and shortcomings:

One of the standout features of these lights is their remarkable brightness. These lights effectively illuminate the road and trails, providing excellent visibility even in the darkest of conditions. They offer a range of light modes, including high beam, medium beam, low beam, and various flashing options. This versatility ensures that you can adjust the light output to suit your specific riding environment, whether on well-lit roads or dark trails.

The dual front light design is noteworthy. It consists of two different light sources: a bright cool white LED spotlight and a warm white main beam. This dual lighting setup allows for a broad, blended beam pattern that is similar to car headlights. The options for both light sources and various brightness levels make these lights adaptable to different riding situations.

The built-in power meter displaying the remaining battery percentage is a handy feature. It keeps you informed about the battery status at all times. These lights also serve as a power bank, with a USB port for charging your devices on the go, adding extra functionality to this budget-friendly set.

While these lights have several commendable features, there are some shortcomings that need attention. Some users reported concerns about the battery life, particularly when using both high beams simultaneously. The high beam settings can quickly drain the battery, which may limit their use on longer rides. Users might need to adapt their settings to balance brightness and battery life.

The attachments for both the front and rear lights raised some durability concerns. In particular, the attachment brackets were considered somewhat delicate and may not withstand rough terrain or vibrations from off-road riding. Additional securing measures, like cable ties, might be needed to ensure a stable attachment.

The front light, despite its overall performance, can experience some shaking and might loosen during rides on bumpy terrain. This issue could be addressed with improved vibration-resistant mounting solutions.

The Knog PWR Mountain MTB Lights are undoubtedly powerful. They provide ample illumination for both daytime and nighttime riding, making them highly visible to other road users. These lights meet the crucial requirement of ensuring safety during daytime rides, making them versatile for various cycling conditions.

One noteworthy feature of the PWR Mountain Bike light is its versatility. Besides its primary function as a bike light, it offers additional functionality as a portable power source. This versatility means it can not only light up your path but also power your cell phones and Bluetooth speakers on the go. The capability to serve multiple purposes makes it a practical choice for cyclists.

Durability is a key strength of these lights. They are built robustly, giving riders confidence that they’ll last for many years. Even though the light might be slightly larger and heavier than expected, this robust construction ensures its reliability and longevity.

Despite their power and versatility, these lights are not without their shortcomings. One of the prominent issues is the mount’s stability. The bike mount provided with these lights may not adequately secure the light to the handlebars, especially during rides over rough terrain. The weight of the battery unit can lead to instability, and it may not stay securely attached to the bars.

To address this mounting concern, users may need to purchase the top tube mount and an extension cable, which adds to the overall cost. While these accessories can improve stability, it’s an additional investment that some users might find inconvenient.

The NiteRider Lumina Helmet Light impressed me with its brightness and quality. It delivers excellent illumination, giving you the confidence to tackle those challenging terrains, even during the darkest nights. This feature ensures a safer and more enjoyable cycling experience.

One standout feature is the value you get for the price. The package includes both front and rear lights, making it a fantastic deal. In fact, the quality and performance of these lights would typically cost the same as a front light alone, making this a quality purchase.

The front light, Lumina Micro 900, lives up to its name by offering superb brightness. It effectively lights up your path, allowing you to ride confidently in low-light conditions. The intensity of the front light ensures excellent visibility and enhances safety.

The rear light, while extremely bright, takes visibility to another level. It’s so bright that you could humorously compare it to guiding a lost plane. This high level of visibility is crucial for ensuring you’re seen by other road users, which is especially important for nighttime cycling.

One notable shortcoming I encountered with the NiteRider Lumina Helmet Light is related to its securing mechanism. The clip designed to secure the lights may prove to be ineffective. In my experience, the front light slid into the securing ring but didn’t clip securely in place. This lack of secure attachment can lead to issues, as the light could potentially fall off during a ride, which poses a safety risk.

The rear light fitting was also problematic. In some cases, the rear light fitting was too small for a standard-sized helmet, requiring makeshift solutions to ensure a proper attachment. This design flaw raises concerns about the overall quality and ease of use of the product.

Another concern that arose from user reviews is the battery reliability. Some users reported battery failures, with an estimated 20 percent experiencing issues with the product’s functionality. This suggests a possible inconsistency in product quality that potential buyers should be aware of.

What You Can Look In Mountain Bike Lights Under 100 UK

Unboxing and Comparison

Understand your needs & Brand Comparison

Understanding your needs is the first step in finding the right mountain bike light for your rides. Consider the type of riding you plan to do, whether it’s at night, during the day, or in cloudy conditions. Each scenario requires different lighting solutions. If nighttime riding is your preference, you’ll want a light that offers enough brightness to illuminate your path without blinding fellow cyclists.

For daytime rides, a midday light might suffice. However, for serious nighttime riding, it’s best to invest in a light designed specifically for that purpose. Similarly, if you’re riding in foggy conditions, you’ll need a light that can cut through the fog effectively without causing excessive glare. By carefully assessing your requirements, you can select the ideal mountain bike light for your journeys.

When searching for the best mountain bike light to meet your needs, it’s crucial to explore various brands. Different manufacturers offer a range of features and benefits, often at competitive prices. This diversity makes it easier to identify the best value for your money. It’s not just about brightness; factors such as the light’s weight, waterproofing capabilities, and mounting options should also be taken into consideration.

By comparing multiple brands, you can make an informed decision and select the mountain bike light that aligns perfectly with your riding preferences and requirements.


Many riders tend to assume that because the lights themselves are compact, the batteries should be lightweight too. However, the reality is that the batteries used in mountain bike lights are quite substantial. The reason behind this is the necessity for high-capacity batteries to power the exceptionally bright lights required for nighttime trail riding.

For years, the prevailing notion has been that mountain bike lights should be as lightweight as possible. After all, when you’re tackling steep inclines, every ounce can make a difference. Nevertheless, there are some advantages to using heavier lights. Heavier lights tend to be more stable, making them less likely to come loose during a ride. Additionally, these lights often boast superior durability and construction, which can be a significant advantage on the trails.

Bar Mount & Installation

When it comes to mounting mountain bike lights, one of the most common options is a bar mount. As the name suggests, it securely attaches to your handlebars, ensuring an unobstructed view of the trail ahead. There’s a wide variety of bar mounts available, but they all share a common goal: keeping your light firmly in place, no matter how rough the terrain gets. When selecting a bar mount, it’s essential to consider the size and shape of your handlebars. Make sure to double-check compatibility before making your purchase, as some mounts are designed specifically for certain types of lights.

Now, let’s talk about the installation process. There are primarily two kinds of mountain bike lights for installation: handlebar-mounted and helmet-mounted. Handlebar-mounted lights are excellent for trail riding, as they tend to be more budget-friendly and offer a broader beam pattern. On the other hand, helmet-mounted lights, while pricier, have a narrower beam pattern, making them a great choice for navigating challenging terrain at night. Depending on your specific needs, you’ll want to choose the right type of light.

Once you’ve selected the lighting system that suits your requirements, it’s time for installation. For handlebar-mounted lights, you can follow the instructions included with the light, making it a straightforward process. Helmet-mounted lights require a separate mounting mechanism, so you’ll need to install the mount first and then attach the light as directed.

When utilizing a bike light, battery life is always an issue since a dead battery might leave you stranded in the dark at the worst possible moment. It’s crucial to understand how to keep an eye on your bike light’s battery level because of this.

There are many of mountain bike lights available without an integrated battery level display. For cyclists who find themselves suddenly without a light source in the midst of a ride, this may be irritating. It is hard to plan ahead and make sure you have enough light to finish your journey safely if you don’t know how much power the batteries have left. To solve this issue, many riders bring additional batteries, however this makes your saddlebag or backpack heavier and more cumbersome.

Investing in a mountain bike light with an integrated battery level indicator is a better option. This makes it simple to keep an eye on your power level and ensure you have enough illumination for the duration of the journey. This is not only more practical, but it also lessens the likelihood of unplanned mid-ride malfunctions.

How We tested the Mountain Bike Lights?

2. Brightness and Beam Patterns: We evaluate the brightness of the lights and their beam patterns. We assess how well they illuminate the trail or road ahead without blinding other cyclists or pedestrians. We look for a good balance between a clear view of the path and safety for others.

3. Battery Life: We test the battery life under different settings (high, medium, low, and flashing modes). It’s essential to know how long the lights will last on a single charge to plan rides accordingly.

4. Mounting and Installation: We assess how easy it is to mount and install the lights. This includes checking the compatibility of bar mounts, helmet mounts, and the ease of following installation instructions.

5. Durability and Construction: We examine the build quality and durability of the lights. This includes assessing whether they can withstand vibrations, impacts, and adverse weather conditions.

6. User-Friendliness: We evaluate the user-friendliness of the lights, such as how easy it is to switch between light modes, adjust settings, and whether they come with user-friendly accessories like wireless controllers.

7. Customer Feedback: We consider customer reviews and feedback from riders who have used these lights. This provides insights into long-term durability, common issues, and overall user satisfaction.

8. Price and Value: We also factor in the price of the lights and assess whether they provide good value for the features and performance they offer.

By conducting these comprehensive tests, we aim to provide riders with valuable information to make informed decisions when choosing the best mountain bike lights for their needs.
