Available as a standalone unit or as part of the Evo Downhill package with the Trail Evo, the Hangover excels in trail illumination and ease of operation, making it a top recommendation for most riders.
Mounting the Hangover is exceptionally simple thanks to the included curved action camera mount, compatible with most helmets. Outbound Lighting also provides additional base options for unique helmet shapes, ensuring a secure fit. Its lightweight and low-profile design mean you’ll barely notice it during your ride.
User-friendliness extends to operation, with a large, raised single button that’s easy to locate and use, even with gloves. The indicator light clearly displays the current mode and remaining battery, a thoughtful touch that simplifies use compared to many other lights.
On the trail, the Hangover shines with its wide beam pattern, ideally suited for technical, medium-speed trails up to 20 mph. It eliminates tunnel vision, providing comprehensive visibility. While it might require slight angle adjustments for very fast, straight trails to maximize beam distance, its performance is exceptional for the vast majority of night riding scenarios.

The adaptive mode intelligently adjusts brightness based on ambient light, conserving battery while maintaining consistent visual effectiveness as your eyes adjust to darkness. Conveniently, it can also be charged while riding via a USB-C connection.
The Outbound Lighting Hangover became our most frequently chosen helmet light during testing. Its wide, detail-rich beam and user-friendly design, combined with a competitive price, make it an excellent investment for serious night riders.

- Type: Handlebar
- Max Lumens: ≈ 2200
- Battery: 10,000 mAh internal
- Burn Time: 1.7 hrs (high), 2.6 hrs (adaptive), 8.5 hrs (low)
- Weight: 275 g (light), 42 g (mount)
- Mounts Included: Quick-release handlebar mount
Pros:
- Exceptionally well-designed handlebar clamp
- Wide and expansive beam pattern
- Excellent user experience
- Integrated internal battery
Cons:
- Beam reach may be limited at very high speeds
The Outbound Lighting Trail Evo ($245), the handlebar counterpart to the Hangover helmet light, delivers approximately 2200 lumens through nine LEDs, casting a wide and even beam across the trail. Available alone or in the Evo Downhill package with the Hangover, the Trail Evo mirrors its helmet-mounted sibling in providing outstanding visibility and user-friendliness, thanks to its internal battery, intuitive controls, and sturdy handlebar mount.
The handlebar mount is a standout feature, positioning the light centrally in front of the stem and incorporating cable management to prevent shadowing. Its pivoting clamp allows for easy attachment and removal, while maintaining a secure and low-profile setup.
The quick-release mechanism for detaching the light body is durable, user-friendly, and stable. Adjusting the light angle is tool-free and independent of the clamp, simplifying trail-side adjustments regardless of terrain pitch.
Similar to the Hangover, the Trail Evo excels in 95% of night riding scenarios. While its wide beam pattern might be outrun at extremely high speeds on straightaways, it provides ample power for most riding conditions, offering excellent visibility of trail features without causing eye fatigue or tunnel vision.
When paired with the Hangover helmet light as the Evo Downhill Package, the combination offers a superior user experience unmatched in the market today.
The Trail Evo offers the same modes as the Hangover: low, medium, high, and adaptive. Its 10,000 mAh internal battery delivers run times of 1:45 (high) to 2:35 (adaptive), allowing riders to confidently start their ride in high or adaptive mode and focus on the trail ahead.
For longer rides, switching to low mode for climbs and high or adaptive for descents efficiently manages battery life. The clear battery indicator further aids in battery management.
While the Exposure Six Pack Mk13 offers more raw power, the Trail Evo provides exceptional performance at less than half the price, making it a more practical choice for most night riders.
The Trail Evo’s exceptional user experience, wide and consistently bright beam, and streamlined mounting make it a top recommendation for anyone serious about investing in a high-quality mountain bike lighting system. The Evo Downhill package, combining the Trail Evo and Hangover, is particularly compelling for a complete lighting solution.

Niterider Lumina Pro 1200
Check Price at Performance Bike
Niterider Lumina Pro 1200 helmet light showing its versatile handlebar and helmet mounting options
Key Specs:
- Type: Helmet or Handlebar
- Max Lumens: 1200
- Battery: Internal (unspecified capacity)
- Burn Time: 55 min (high), 7 hrs (low)
- Weight: 193 g
- Mounts Included: Handlebar (Helmet mount sold separately)
Pros:
- Affordable price point
- Simple and intuitive operation
- Stable, tool-free handlebar mount included
- Versatile for both handlebar and helmet use
Cons:
- Shorter battery life in Boost Mode
- Slightly heavier for helmet mounting compared to premium options
The Niterider Lumina Pro 1200 ($115) is a 1,200-lumen light offering dual functionality as both a handlebar and helmet light. The handlebar mount is included, while the helmet mount is available separately. Featuring colored LEDs to indicate battery life and mode, simple two-button operation, and secure mounting options, it stands out for its versatility and value.
The Lumina Pro 1200 includes a travel lock mode, preventing accidental battery drain during transport. Setup is straightforward; unlocking the light is the only initial step. Two buttons and indicator lights make mode selection and battery monitoring easy. The tool-free handlebar mount is quick to set up, and a full charge is achieved in just over 4 hours.
It offers five steady output modes ranging from Walk (65 lumens for 20 hours) to Boost (1200 lumens for 55 minutes), plus three pulse modes with 8-hour battery life. The two-button design allows for easy toggling between settings, including direct access between High and Medium modes, a user-friendly feature not always found in single-button lights.
On the trail, the Niterider Lumina Pro 1200 delivers reliable performance. While not as bright as premium options like the Exposure Zenith or Six Pack, and lacking the wide flood beam of Outbound Lighting models, it provides sufficient power for most night riding scenarios.
Boost mode, offering maximum brightness, has a shorter 55-minute battery life, requiring riders to manage usage, especially on longer descents. However, with strategic use of lower modes for climbs, battery life is sufficient for 1- to 3-hour rides, with the battery indicator providing reliable feedback.
The beam pattern is more focused, a spotlight style, compared to Exposure and Outbound Lighting, but offers competitive peripheral flood capability similar to lights like Lezyne Lite Drive 1200+ and Macro Drive 1400+. For aggressive trail riding, pairing the Lumina Pro 1200 as a helmet light with a wider beam handlebar light is recommended.
For handlebar use, while sufficient for winter fat biking and slower rides, a more powerful light might be preferred for faster summer trail riding. The helmet-mounted weight is noticeable but manageable.
At $115, the Niterider Lumina Pro 1200 is a versatile and budget-friendly choice, excellent for commuters who also want to explore occasional night trail rides. It’s a dependable, easy-to-use light that performs consistently for most moderate-paced trail riding.

Fenix BC30 Bike Light V2.0
Fenix BC30 V2.0 handlebar light highlighting its compact design and wireless remote
Key Specs:
- Type: Handlebar
- Max Lumens: 2200 (burst), 1500 (high)
- Battery: 2 x 18650 rechargeable Li-Ion batteries (not included)
- Burn Time: 2.3 hours (high)
- Weight: 154 g
- Mounts Included: Handlebar
Pros:
- Affordable price point
- High brightness for the price
- Replaceable batteries for extended rides
- Wireless handlebar remote control
Cons:
- Batteries need to be purchased separately
The Fenix BC30 V2.0 ($120) offers impressive features at an accessible price. Unique in this guide for using replaceable batteries (2×18650 or 4xCR123), it has been a reliable choice for expedition racers for years, including testers Chelsey and Jason Magness.
The V2.0 includes a wireless remote control, enhancing safety by allowing mode changes without removing hands from the handlebars on technical terrain.

However, this comes with a trade-off in waterproofness.
While rated IP67 for robust water protection when sealed, changing batteries in wet conditions requires caution to prevent water ingress into the battery compartment, which could lead to short circuits.
Another factor is that the BC30 V2.0 is sold without batteries, requiring an additional purchase. While this adds to the initial cost, the ability to carry spares and extend ride times is a significant benefit for longer adventures. For everyday rides, however, the simplicity of internal rechargeable batteries, like those in the Light & Motion Seca Comp 2000, might be preferred, despite the higher price point of such integrated systems.
Overall, the Fenix BC30 V2.0 stands out for its ease of use, brightness, and respectable run times, making it a strong handlebar mount option, or helmet light with an optional mount, that delivers excellent value without breaking the bank.
Best Premium Mountain Bike Helmet Light
Exposure Zenith Mk3
Exposure Zenith Mk3 helmet light showcasing its machined finish and compact form factor
Key Specs:
- Type: Helmet or Handlebar
- Max Lumens: 2200
- Battery: 5,000 mAh internal
- Burn Time: 1 hr (high), 18 hrs (low)
- Weight: 147 g (light), 11 g (mount)
- Mounts Included: Handlebar, Helmet, GoPro (adapter not included)
Pros:
- Exquisitely machined construction
- Powerful spotlight beam suitable for helmet use, yet wide enough when combined with handlebar lights
- Eight versatile modes
- Long beam throw, hard to outrun at high speeds
- Doubles as a high-quality flashlight
- Built for exceptional durability
- Premium packaging for secure storage
Cons:
- Included helmet clamp may not fit all helmet designs
- High price point
- Longer charge time
The Exposure Zenith Mk3 ($320) is a top-tier helmet light, though its premium price might be a barrier for some. It boasts a beautifully machined finish, a 2200-lumen max output, eight mode options, and a potent spot beam, making it ideal for serious night riders seeking top-end performance.
The Zenith Mk3’s helmet mount uses a unique vent clamp system that secures to the top and inside of the helmet shell, working well with most helmets. For helmets with incompatible vent designs, an action camera mount adapter can be purchased separately for $10, ensuring stable mounting. The inclusion of a lanyard enhances its utility as a powerful, everyday flashlight off the bike.
Initial setup is slightly more involved than simpler lights like the Outbound Lighting Hangover, but the range of modes justifies the initial setup effort. Features include TAP mode, which allows brightness adjustment by tapping the light body, useful for racing or frequent adjustments, though some testers preferred the standard button operation.
Mode options are extensive, with modes like Mode 1 (1 hour high, 3 hours medium, 6 hours low) and Mode 4 (1 hour high, 3 hours medium) fitting typical night ride durations. Battery life is ample for most rides, and the 3-hour medium setting is sufficient for climbs, with a 6-hour low setting available for extended use.
On the trail, the Zenith’s beam is more of a spotlight, ideal for a helmet light, especially when paired with a flood beam handlebar light like the Exposure Six Pack Mk13. This combination provides daytime-level visibility.
The Zenith’s 2200 lumens and long beam throw ensure you’ll never outrun the light. Its focused beam complements wider handlebar lights like the Outbound Trail Evo, offering a balanced lighting setup.
While the Outbound Hangover is our top overall helmet light recommendation due to its broad appeal, the Zenith Mk3 represents the pinnacle of helmet light performance for those prioritizing maximum capability and durability, justifying its higher cost for dedicated night riders.

It’s our top pick for serious night riders seeking a robust, user-friendly, and exceptionally bright light. Its machined construction ensures long-lasting performance.
An LCD screen displays the selected program, setting, and remaining battery life, simplifying setup and trail-side adjustments.

The 17,000 mAh battery provides a minimum 2-hour burn time on high (3900 lumens) and up to 36 hours on low, catering to diverse riding needs. Mode 1 with Reflex++ technology automatically adjusts brightness based on riding conditions, eliminating manual adjustments for rides under 3 hours.
Reflex++ technology utilizes 3D digital accelerometers, gyroscopes, and thermistors to intelligently adjust brightness. It learns rider style over 20 minutes and continuously adapts to optimize output based on speed and terrain.
In Mode 1, Reflex++ maximizes runtime to 3 hours while delivering up to 5450 lumens for fast descents. It reliably provides optimal brightness automatically, dimming on climbs and brightening on descents.
The Six Pack Mk13 provides superior visibility compared to any other light tested, making it ideal for aggressive night riding. Its wide beam pattern illuminates both the trail and periphery, with a long throw that eliminates any chance of outrunning the light. While heavier at 404 grams, the sturdy handlebar clamp ensures stable and quiet performance.
Despite its high $536 price, the Exposure Six Pack Mk13 is a long-term investment in top-tier performance and durability. For dedicated night riders, its exceptional brightness, Reflex++ technology, balanced beam pattern, and robust build quality justify the cost, making it the ultimate mountain bike light.

Knog Blinder X 1800 handlebar light with external battery and remote, showcasing its versatile mounting optionsKey Specs:
- Type: Handlebar or Helmet
- Max Lumens: 1800
- Battery: 10,000 mAh external
- Burn Time: 2.5 hrs (high), 6.5 hrs (med), 15 hrs (low)
- Weight: 153 g (light/mount), 280 g (battery)
- Mounts Included: Handlebar, Helmet, Battery mounts
Pros:
- Includes both helmet and handlebar mounts
- Wired handlebar remote control
- High brightness output
- Excellent beam throw and spread
- Long run times
Cons:
- External battery pack adds complexity
- Heavier system weight
- Helmet mount may not be universally compatible
Knog, known for commuter lights, enters the off-road market with the Blinder X series, available in 1800 and 2300-lumen models. These lights offer impressive brightness, long run times, and a well-rounded design, though minor quirks prevent them from topping our overall rankings.
Both models share identical form factors and included accessories: a 10,000 mAh external battery pack with frame and bottle cage mounts, handlebar mount (with shims for 31.8 and 35 mm bars), strap helmet mount, remote mount, and a 700 mm extension cable.
With both handlebar and helmet mounts included, testers used the 2300 on handlebars and the 1800 on a helmet. The handlebar mount is a stable hinged clamp, while the helmet mount uses Velcro straps through helmet vents, proving surprisingly stable, though potential compatibility issues exist depending on helmet vent configuration. Angle adjustments require tools for both mounts.
Battery pack mounting offers frame or bottle cage options. Frame mounting, avoiding cable extension, proved stable. Helmet mounting used the extension cable with the battery stashed in cargo bib pockets, functional but slightly cumbersome like any external battery system.
The wired remote easily mounts to handlebars and helmets with magnetic straps or stick-on mounts. It toggles through light modes and indicates brightness settings, while the battery power button shows remaining charge.
Blinder X lights are exceptionally bright with a focused beam and excellent peripheral spread, providing daylight-level visibility on high mode. A remote tap dims to medium, then low (350 lumens).
Run times are impressive, with the 1800 model offering 2.5 hours and the 2300 model 1.8 hours on high, and triple that on medium.
The Blinder X series is a strong contender for serious night riders. However, the external battery adds setup complexity compared to self-contained units. Angle adjustments require tools, and the combined light and battery system is heavier at 433g. Despite these minor drawbacks, these bright and well-performing lights are a valuable addition to the mountain bike light market.

- Easy to attach and detach
- Sufficient brightness
Cons:
- Shorter burn time on high
- Rubber handlebar strap mount is less secure than clamp mounts
The Light & Motion Seca Comp 2000 ($230) offers a refreshing simplicity compared to more complex, feature-rich models. It’s a straightforward package: light, handlebar mount, and charging cord.
This self-contained unit is intuitive and bright, delivering 2,000 lumens. Its beam pattern is well-designed, combining a spot beam for distance and a wide fill for periphery. With a 1.5-hour burn time on high, it suits most night rides, especially with mode switching. “Race Mode” simplifies toggling between medium and high settings with a single button press.
Versatile for trails and commuting, it includes daytime visibility modes and optional side lighting. The rubber strap mount is exceptionally easy to use, fitting any handlebar, and facilitates quick removal for charging or bike switching. However, the rubber strap is less secure on very rough terrain and raises long-term durability concerns compared to metal clamps.
Battery life is indicated by a tri-color power button. Full charge time is 4 hours via micro-USB.
The Seca Comp 2000 is ideal for riders who value simplicity and ease of use. It’s bright enough and user-friendly, making it an excellent entry point for night riding. Its versatility suits riders who commute and trail ride.
For serious night riding, the Outbound Trail Evo offers greater brightness and longer burn times. However, the Seca Comp 2000 remains a strong, simple option.

With a max output of 3600 lumens, it delivers daylight-level illumination, with a balanced beam throw and spread. Multiple customizable brightness settings cater to diverse preferences. The included 6,900 mAh battery provides 1.75 hours of runtime on high (3,600 lumens) and 3.3 hours at 1,800 lumens.
Drawbacks include the complexity of the external battery system, requiring wire management and battery mounting, and a very high $650 price. For the price, self-contained systems like the Exposure Six-Pack Mk13 or Zenith Mk3 might be more appealing in terms of simplicity.
However, the Wilma R 7 is a lifetime investment, offering unparalleled modularity and adaptability, making it a compelling option for users who need a highly customizable and expandable lighting system.

Cons:
- 1000 lumen max output is on the lower end for serious night riding
- Rubber mounting system is not the most stable on rough terrain
The Light & Motion Vis Pro 1000 Trail ($130), with 1,000 max lumens, is on the lower end for serious night riding. However, it’s ideal for bikepacking or emergency situations where light weight, portability, and reliability are prioritized over maximum brightness.
The Vis Pro 1000 excels in portability and durability. At 142g and waterproof to 1m, it’s barely noticeable and robust. Its self-contained design easily switches between handlebar and helmet use, even functioning as a headlamp. The strap mount allows quick attachment to any handlebar and easy removal.
Charging via USB takes 2.5 hours. It can operate at 150 lumens while charging, sufficient for extended gravel rides to camp. It runs for 1.5 hours on high and up to 6 hours on low (250 lumens), suitable for unexpected late finishes.
The beam pattern is less ideal for high-speed singletrack, and the rubber mount is not perfectly stable on very rough terrain. However, it’s an excellent light to pack for bikepacking or evening rides where darkness might unexpectedly fall.

- Battery: 8-cell Li-Ion external
- Burn Time: 1.5 hours (high), 16.5 hours (600 lumens)
- Weight: 1406 g (total system)
- Mounts Included: Handlebar
Pros:
- Extremely bright 4,200 lumen output
- Long burn time at lower settings
Cons:
- High price point
- Heavy system weight

Types of Riding
Mountain bike lights vary as much as riding styles. Choose lights suited to your typical riding. This includes brightness, battery size, and form factor.
Faster, more technical riding demands brighter, more stable lights. Lower speeds and smoother terrain require less brightness, but adequate illumination is always necessary. We recommend using both helmet and handlebar lights for optimal visibility in all conditions.
Consider ride duration. Most lights suffice for typical couple-hour rides. For all-night riding, choose lights with extended run times. Winter snow riding often requires less brightness due to snow’s reflective properties.

Helmet vs. Handlebar Mounts
Mountain bike lights mount on handlebars or helmets. A combination is ideal for night riding. While one or the other is usable, both offer superior visibility. Many lights come with one or both mounting systems, and aftermarket mounts allow location switching.
Handlebar lights point in your travel direction, moving with steering but not always directly where you look. Hinged clamp mounts, tightened with Allen keys, are most secure and stable, often with shims for 31.8mm and 35mm handlebars.
Lighter lights use stretchy rubber straps for tool-free, easy mounting, but are less secure than clamp mounts. Mount handlebar lights close to the stem for centered positioning.

Helmet lights move with your head, pointing where you look, and offer higher light source, casting light over obstacles. Essential for technical terrain, helmet lights enhance visibility in turns and varied landscapes.
Helmet mounts often use Velcro straps through helmet vents, or stick-on, clip-on, or action camera mounts.
Helmet light drawbacks include potential mount instability (especially strap types) and bounce during rides. Light weight on the head can require helmet tightening for stability. Most helmet lights are under 200g, minimizing weight impact.
