As someone who’s spent many evening and early morning hours on the trails, I’ve come to appreciate how incredibly useful a good light setup is — especially when riding through dim, twisty paths or pushing past traffic on a road after a long day. Whether it’s a cool summer night or the chill of winter, the right systems can turn a sketchy descent into a smooth experience.
There are a surprising number of budget-friendly options out there that don’t skimp on quality. A proper kit doesn’t have to be expensive — the best mountain bike lights under 100 are proof that fair-priced gear can still deliver stellar performance.
Many riders, including bikepackers, find themselves pedaling through the night, especially when days are short. I’ve tested several lights myself, and while compiling this list, I prioritized what’s actually useful in real-world conditions. Factors like temperatures, late departures, and unexpected delays make a strong, dependable light more than just a gadget — it becomes a necessity. From mountain biking in low-light conditions to commuting safely on a bike, these lights help ensure you’re never caught in the dark.
Best Mountain Bike Lights Under 100
1. Best overall

NiteRider Lumina 1200 Boost
Specifications
Lumens: Delivers a bright 1200 lumens of focused power
Weight: At just 172g, it’s surprisingly compact yet feels tough enough for rugged terrain.
Mount: Comes with a solid and universal mount that fits easily on most handlebars.
Display: The OLED option gives real-time battery and mode updates.
Charging: It features fast charging capability
Reasons to buy
Press the instant boost button when you hit darker stretches or sudden descents—it really helps you stay confident and in control.
The safety lock function avoids accidental turn-ons in your gear bag, something I’ve had issues with in other lights.
Its small form factor makes it ideal for both minimal setups and bikepackers trying to save space.
Reasons to avoid
The beam spread is limited, with not much peripheral lighting—great straight ahead, but you’ll miss those side views.
No shiners on the side, so it may not be the best for city rides where side visibility matters.
The battery is on the smaller side
I tested the NiteRider Lumina 1200 Boost on a few early morning rides and was impressed by how brighter it looked than I’d initially expect from a unit rated at 1,200 lumens. Even in full-power mode, the light had a strong punch, allowing me to clearly see every twist and turn on the trail. The beam at full blast lit up the ground with confidence, although I had to be careful with runtime since the battery only lasted about an hour in that setting.
Thankfully, there are multiple modes to stretch out battery life. I usually switched to a medium setting of around 550 lumen, which gave me close to three hours of solid visibility. During my review, I appreciated the flexibility and compact power this light offers. While the battery is a bit small compared to some pricier lights, this one balances performance and cost beautifully—especially for riders seeking performance without overspending.
2. Best combo light set

Cateye AMPP 1100 / AMPP 800 combo light set
Specifications
AMPP 1100 delivers a strong 1100 lumens with broad beam patterns.
The AMPP 800 puts out 800 lumens, and it’s incredibly lightweight at just 143g, while the 1100 version weighs 223g.
Both lights feature a universal bar fit.
The set includes a bundle that gives you a free mount.
Fast recharge and instant emergency max modes make both lights efficient and rider-friendly in real situations.
Reasons to buy
I found the power delivery smooth with slow transitions that helped avoid harsh lighting jumps during technical rides.
The lights are compact but very useful for commuting and trail use alike.
The combo works well even as a helmet + handlebar pair due to its light weight and flexible mounting system.
Reasons to avoid
The helmet mount is a bit tall, which can feel awkward depending on helmet shape.
I noticed the GoPro-style shoe is slightly mis-shaped, making it hard to secure without patience.
The bracket dial requires extra care during installation to avoid overtightening or stripping the thread.
The Cateye AMPP 1100 and AMPP 800 combo is a powerful set for riders who want full trail coverage without breaking the bank. One light is handlebar-mounted and does the heavy lifting, throwing out a bright beam that follows your handlebars and lights up the path ahead.
The other is helmet-mounted, helping you spot details around corners and enhancing peripheral vision. Together, the lights produce a total of 1,900 lumens, making it easier to ride fast and safe through the dark. I’ve tested it during nighttime runs through the forest, and the clear shine it casts on every trail turn is seriously confidence-boosting.
What stands out is how decent the price feels when you realize you’re getting both a helmet and handlebar setup in one combo. Though this model is listed at $165, it earns its spot on any recommended list simply because it performs like a much more expensive system.

Very minimal modes to choose from — it lacks some flexibility found in other units.
The LifeLine Pavo 1400 Lumen Motion is one of the few budget bike lights that really delivers on power without compromising on battery life. It puts out up to 1400 lumens, lighting up both trail and road effortlessly, and keeps running at full brightness for a solid 2.5 hours—perfect for long night rides. With a smart motion feature and speed-sensitive control, it automatically halves the light output when you’re at a standstill, helping to conserve battery and extending your ride time. The motion setting drops 700 lumens down to 350, making it efficient yet still useful in darker spots.
It includes a compatible handlebar mount that fits both 31.8 and 35mm bars, and its small size even works great as a helmet mount (though that’s sold separately). I liked the minimal layout—it comes with three constant codes and one flash mode, keeping things simple when you’re in motion.

This little unit can produce up to 1000 lumens, holding full blast for 1.5 hours, which is perfect for trail riders needing brightness deep into a ride. If you’re just after some visibility for road or daytime riding, there’s a 15 lumen mode that stretches up to 80 hours, which I’ve used during commutes and found surprisingly effective. It really hits the sweet spot between strength and runtime for a great price of just $80.
What makes it even more appealing is the option to grab a fully-loaded kit, which includes a remote switch, mounting strap, and charging cable—although it may be sold out from time to time. You also get a choice of colors, which is a unique feature in this light market. I personally love that touch—it lets you match your setup with some flair. The light is strong, customizable, and reliable, making it one of the smartest buys for under 100.
5. Best innovative

Specialized Flux 850
Specifications
Offers 850 lumens.
Uses a unique double beam pattern that helps spread the light more evenly for better coverage.
Weight is unpublished.
The mounting setup is part of a smart system.
Reasons to buy
The price makes it a good value, especially given the clever beam configuration and solid construction.
It holds up well in real-world conditions without trying to oversell itself as overly powerful.
Reasons to avoid
The mounting hardware can feel a bit complicated at first, especially compared to more streamlined lights.
Since the weight is unpublished, some weight-conscious riders might hesitate if they’re dialing in a precise setup.
The Specialized Flux 850 is a thoughtfully designed light that stands out for its unique mounting system. It can be mounted on top of the handlebars, at level, or even on the underside, which I found handy depending on the terrain and bike setup. It securely bolts onto 22.2, 25.4, or 31.8mm bars, so it’s compatible with most modern bikes. It isn’t the most powerful on the list, but it has a brighter, wider beam that provides a strong field of view, and its brightness rating of 850 lumens at 1.5 hours of run time is more than enough for most night rides.
This double beam pattern is really what sets the Flux 850 apart—it gives off a clean spread of light that improves visibility without blinding oncoming riders. Its battery life balances well with brightness, and for a price of $80, it’s a truly affordable option. The novelty of this setup doesn’t stop at design; it’s also accessible at nearly any shop that stocks Specialized gear. If the more intense 1200 lumen version feels like overkill, the 850 is the sweet spot many riders will prefer.
6. Best minimalist rear light

Specialized Flashback
Specifications
Emits 20 lumens.
Weight remains unpublished, but based on my usage, it feels extremely light and easy to handle.
Mounts easily and securely on almost any surface—this one truly fits nearly anywhere on your bike.
Reasons to buy
It’s incredibly cheap, making it a smart backup or budget-friendly rear light for occasional use.
Perfect for commuting or quick evening rides when you don’t need the brightest beam.
It is perfect for minimalist installations because of its tiny size.
Reasons to avoid
At 20 lumens, this isn’t for lighting your path—it’s purely for visibility.
Since the weight is unpublished, it might not satisfy riders who like to track every gram.
The Specialized Flashback is a great companion to your front light, especially for those moments when you’re finishing a trail riding session and hit the road. While a rear light isn’t always essential for off-road trails, it becomes extremely useful if you’re navigating traffic or vehicle zones mid-route. At just $20, it’s surprisingly affordable for the safety it adds.
It has a flash mode of 20 lumens that runs for four hours, a steady mode at 10 lumens that lasts two hours, and an even more energy-efficient mode at 5 lumens for extended use

Weighs only 69g, making it extremely light and ideal for those wanting to reduce weight on their ride.
Designed to be small yet effective.
Includes a flexible strap mount for quick on-off transitions.
Reasons to buy
Offers a bright and clear beam that makes you visible from a distance, improving safety.
The price is very good for what you get — an ideal choice for new riders or as a secondary light.
Reasons to avoid
The mounting strap can feel a little fiddly, especially in cold weather or when wearing gloves.
The Lezyne Zecto Drive Max is a small, lightweight rear light that provides dependable power. It provides 250 lumens while flashing and runs for up to nine hours, which is great for evening or night rides. Drop it to 125 lumens and it’ll flash for as long as 14 hours, making it perfect for long commutes or multi-day adventures.
I’ve used it on rides deep into the forest, and it kept me clearly visible to traffic and fellow buddies. It’s also super easy to mount using the integrated clip and strap system, which works well on most bike setups.
What makes this light stand out is how bright it is despite its size, and for just $50, it’s a really good deal.

How to choose the best budget mountain bike lights
How bright should lights be?
When riding your mountain bike through dark woods, a bright light isn’t just helpful—it’s essential. Your speed plays a huge effect on how much lumen or lumens your light needs, especially when approaching obstacles fast. I’ve found that around 1000 lumens is a solid middle ground for most trail conditions, but some riders may need even brighter lights depending on the terrain. More powerful output usually comes with higher dollars and shorter battery life, so finding the right balance is key.
How much does battery life matter?
Battery life is one of the most important things to consider when choosing lights from this list, especially if you plan to ride deep into the dark. Running your light at maximum brightness might look great, but it’ll drain the battery much faster—sometimes lasting only 1.5 hours at full blast. I’ve learned to switch to a less-bright mode when not bombing down trails, which has dramatically increased runtime. Make sure to check what your light is capable of, because the right mode can be the difference between cutting a ride short or making it home safely.
Should I have a rear light?
While rear lights may not feel necessary for mountain biking on singletrack or trails, they can be extremely helpful in real-world riding scenarios. I’ve had a few moments where a buddy got separated during a night ride, and a bright rear light helped us regroup. It’s also just smart for safety, especially if you’re commuting from the trail to the road, or rolling into town. Rear lights make you more visible to drivers in traffic, and when riding paved or gravel paths, they’re pretty much essential.
The good news is that a basic rear light doesn’t cost much—there are plenty of reasonable prices for lights that do the job well. They don’t need to be as powerful as front lights, and even a small one can give you a long run time in dim light conditions. If you’re out on roads at dusk or commuting after dark, the extra visibility is worth it.
