How to Choose a Bicycle Light

There are so many different brands on the market, each with a variety of settings and lumens. How do you go about choosing the best one?

The first thing you need to consider is when you're going to use the light, this will determine the number of lumens you need. Daytime cycling requires much higher lumens than traveling at night. If you commute to work in daylight, your front light must be bright.

You'll also want to pair your front light with a rear light that has a flashing function. If you're never going to cycle at night, the very least you'll need is a flashing tail light, but a combo would be better. 

The second consideration is where you'll be riding. Well-lit urban areas will need higher lumens for front and rear lights. If you're cycling on unlit roads or trails, you'll need to be able to see your surroundings. 

Lastly, consider how often you'll be using the light and the weather conditions you'll be riding in. This impacts the durability and IPX4 certification of the unit for which you need to look. In turn, it also affects the price of the device that you're going to buy. 

Review of the Best Bike Lights

To save you time, we've gone out and found the best bike lights available. This round-up will tell you everything you need to know to choose the best light for your cycling habits, including the pros and cons of each light and what users have to say. 

Best Overall:
Ascher AS-3L

Ascher USB Rechargeable Bike Light Set,Super Bright Front Headlight and Rear LED Bicycle Light,650mah Lithium Battery,4 Light Mode Options(2 USB cables and 4 Strap Included)


  • IPX4 certified for all-weather use
  • USB rechargeable lithium batteries
  • Perfect for cycling at night with 80 lumens
  • Four functions on the headlight and tail light
  • Silicon mounting straps make for easy installation


  • Light isn't bright enough for daytime cycling
  • Rubber straps can wear out quickly if you move the lights often

What Recent Buyers Report

The Ascher AS-3L has 8 hours of battery power on specific settings, and users find the product useful on longer rides. Reviews also suggest that even though the straps wear out, you get an extra pair of straps in the packaging, and if you're not hard on the straps, they do, in fact, last.

The lights are bright enough for dusk and nighttime cycling, and users report that if you use the blinking functions, other road users do seem to notice you sooner in daylight. The general level of satisfaction is high. One user even stated that their only regret was not buying two packs of these nifty lights. 

Why it Stands Out to Us

The price of these lights is reasonable, considering that they are sold in pairs. It's a durable unit that you can use in all weather conditions, including rain and snow. The manufacturer also sells the product with a warranty, so if something does go wrong, you have peace of mind that you can replace or repair the device. 

It's easy to install with the rubber bands and clips and bright enough for general road safety. 

The lights are compact and won't get in your way. It's also multifunctional— use it on your bike, backpack, or pet with the same efficiency!

Bottom Line

These lights are affordable and will last a long time. It's not ideal on its own for daytime cycling, but with 80 lumens and a flashing function, it’ll help other road users to see you. 

You can choose the light's function according to your preference, and it includes half and full brightness or fast and slow flashing modes.

Vont Scope Bike Light

Vont 'Scope' Bike Light, Bicycle Light Installs in Seconds Without Tools, Powerful Bike Headlight Compatible with: Mountain, Kids, Street, Bikes, Front & Back Illumination


  • Made for all weather conditions
  • Provides visibility from 1,000 feet away
  • Easy installation on your bike with no tools
  • Made from military-grade materials for ultimate durability
  • 120 lumens for the front light and 15 lumens for the rear with Cree LED technology for optimum brightness


  • Uses 3 AAA batteries and is not rechargeable
  • Power button seems to be a little too sensitive

What Recent Buyers Report

Most reports from recent buyers state that they are thrilled with the device. Users have pointed out how easy it is to install without needing any tools. They love how bright the light is, making nighttime cycling in low-light areas so much easier. The trail riders indicated that they wouldn't use this unit on solitary rides with no additional lighting.

One or two users have been unsatisfied with the light's brightness level, one pointing out that the beam is highly focused and unhelpful on trails. Reports seem to show that those lights may have been malfunctioning, with many users defending the device. 

Why it Stands Out to Us

Besides the fact that these lights use military-grade materials for durability, it also has a premium-quality design. Other road users will be able to see you within 300 feet, leaving enough time for motorists to move out of the way and not pose a hazard.

Bottom Line

The light seems to be indestructible and comes with a lifetime warranty. You'll get value for your money with this device, which is perfect for cycling in well-lit or low-light conditions. You'll be able to install the light quickly, and you'll get at least eight hours of light from the batteries.

Best for the Money:
BV Bicycle Light

BV Bicycle Light Set Super Bright 5 LED Headlight, 3 LED Taillight, Quick-Release


  • Visibility of up to 150 feet
  • Three modes for each light
  • Up to 80 hours of light with the batteries
  • Quick-release mount with adjustable angles
  • Five LED lights for the front and three for the backlight


  • Batteries are not rechargeable
  • Front light is only 35 lumens, and the back is only three

What Recent Buyers Report

Buyers are impressed with the company's customer service, with follow-up and quick action if there is a problem. They also mentioned how easy it is to install the units on your bike. Cyclists are dazzled with the quality compared with the price. 

Many buyers expected a flimsy light that would quickly break but were surprised by what they received. Users happily use the set for night rides, although they report that it's not bright enough to illuminate trails. It’ll work perfectly in well-lit areas or roads that have some lighting. 

Why it Stands Out to Us

This lightweight unit fits almost all bikes easily, and you can install it within minutes. You get the front and rear light in the pack, which means it's a bargain. The light also comes with a one-year warranty that covers any manufacturing defects. 

The lights slip on and off of the mounting easily so that you can carry replacements with you for extended rides. You can also detach it from your bike when you lock it so that the lights don't get stolen. It's bright enough for traffic to see you, making the BV Bicycle light a great safety feature. 

Bottom Line

This is excellent quality for the price, and you won't be sorry if you get these lights for your commutes at dusk or cycling in well-lit areas at night. You won't be able to use them for trail rides or as a safety feature in the day.

Best Bike Lights for Night Riding:
VASTFIRE Mountain Bike Lights

Best Mountain Bike Lights for Night Riding,1000 Lumens Bike Headlight 2 LED【Upgrade Mount】,USB Rechargeable Bicycle Headlight & Rear Light Set for Road Commuting,Front & Back Bike Light Flashing Light


  • USB rechargeable batteries
  • IPX6 waterproof certification
  • Made from aluminum alloy for durability
  • Maximum of 20 hours on specific settings
  • Low-power function to warn you before the lights die


  • Difficult to contact the seller if you need to
  • Mounting brackets could break with many trail rides

What Recent Buyers Report

The only problem buyers seem to have with this light is the bracket that cracks. The rack comes with a lifetime warranty, and the seller will replace it if it breaks. Some buyers have had difficulty contacting the seller. Users rave about the quality that they received for the price they paid.

Why it Stands Out to Us

This light is bright enough for your nighttime trail rides and your daytime commutes. The different functions that the device offers are useful as you can set it to the brightness you need or flash. The bracket's lifetime warranty is a plus because it's the only weak point that this light seems to have. 

The mount keeps the light stable while you're out on the trail. The unit will also let you know when you have to charge the battery, which is another valuable part of the VASTFIRE mountain bike light. 

Bottom Line

You’ll get a great quality light with sufficient brightness at a fair price. It provides safety during the day and illuminates the trails at night. Most users are genuinely impressed with the device and tend to recommend it. If you're looking for a pair of lights that will serve its purpose, you don't have to look any further.

Best Road Bike Lights:

  • 350 lumens

  • USB rechargeable lithium-ion batteries
  • Headlight provides up to 12 hours of light on one charge, and back lights provide up to 11 hours


  • Bracket might not fit your bike
  • Often sold out due to its popularity

What Recent Buyers Report

The consensus with users is that these lights are bright enough for daytime and nighttime traveling. Some users have reported issues with the bracket being too small. It seems like the manufacturer is willing to help buyers with this problem by sending a replacement. 

Some users have stated that they were apprehensive about buying the light, not believing that it could be as bright as claimed, considering the price. They indicated that they were happily surprised. 

Why it Stands Out to Us

The brightness of these lights is perfect for traveling at night, and the flashing function provides visibility during the day. It's a versatile device that you can use for hiking, taking your dog for a walk, or even as a light when you go camping. 

It's easy to install on your bike, and the battery lasts long enough for extended rides. Ascher is a well-known brand in the cycling industry, and you know you're getting a quality product if you buy from them. 

Bottom Line

This is one of the best lights on the market for road cycling. It's bright enough for all your needs, and the four functions add extra safety to your rides. If you mainly travel on the road, you’ll get value for your money when you invest in this light.

Best Mountain Bike Lights:
victagen USB Bike Light

Victagen USB Rechargeable Bike Light, Super Bright Bike Headlight 2400 Lumens and Back Rear Light, Waterproof Bicycle Headlight and Taillight, Easy to Mount Fits for Mountain Road Kids Bikes Cycling


  • Two front lights
  • USB rechargeable batteries
  • Five different light functions
  • 2,400 lumens for optimum brightness
  • Four hours of light on the brightest setting


  • Not a versatile light since you can only use it on your bike
  • Doesn’t have a power bank function like other lights in the Victagen range

What Recent Buyers Report

It's hard to find negative reviews on the victagen USB bike light. One person reported that there was a screw missing to install the light. Some people have seen the design as a little odd. Apart from that, users are delighted with the quality of this unit. 

Cyclists say that they can easily see their surroundings with the ultra-bright light, and it also has enough lumens for traffic to see them, even during the day. Users are also happy with the durability, having lights falling off at over 20mph due to not affixing it properly, and the light still working. 

Why it Stands Out to Us

The fact that you can use this light during the day and at night is undoubtedly attractive in any weather. Add to that the one-year warranty and 30-day money-back guarantee and you know you're getting a quality product. 

The mount is sturdy, and your light won't slip while you're riding on the trails. Not that you'll be hitting any holes, because you'll see them coming. The price of these lights is just as attractive as their functionality. You wouldn't expect the quality that you're getting for the price you're paying. 

Bottom Line

This is easily the best trail light for your bike. Even if you don't ride trails, you'll still find this light handy with your commutes or road cycles. You can use it in well-lit areas as a safety feature or in low-light areas to see and be seen.

Best Bike Lights for Commuting:
Te-Rich Bicycle Lights

  • Cree LED technology to make the most of the 800 lumens


  • Unit is hefty

What Recent Buyers Report

For commuters, trail riders, or those who exercise on the road, this light is a useful tool. Buyers use it as a safety tool to make themselves visible during the day and see their surroundings at night. The overall reviews are positive, stating the fact that the lights are bright enough for any type of cycling. One or two reviewers hinted that the lights come off quickly if you're riding over plenty of bumps. The unit isn't entirely designed for challenging trail rides. 

Why it Stands Out to Us

The Te-Rich bicycle light is a durable unit that emits exceptional light. It's a great safety tool for road cycling and will help your visibility. If you're not completely satisfied with the light, there's a 100% money-back guarantee for one year. 

The batteries' longevity is also quite impressive, allowing for three and a half hours on the brightest function. If you use lower settings, you can ride for up to 40 hours before needing to recharge the batteries. It's a good quality light and perfect for your commutes.

Bottom Line

The Te-Rich bicycle light is sold in pairs. It's one of the brightest lights on the market. It's not designed to ride rugged trails, but you won't easily find better quality or a better price for your everyday riding. Users are happy with the light, and you'll likely be too.

Best Rechargeable Bike Lights:
Vont Pyro Bike Lights

Vont 'Pyro' Bike Light Set, USB Rechargeable, Super Bright Bicycle Light, Bike Lights Front and Back, Bike Headlight, 2X Longer Battery Life, Waterproof, 4 Modes (2 Cables, 4 Straps)


  • Four different modes
  • Rechargeable batteries
  • Compact and lightweight
  • Easy to install on your bike
  • Unit comes with a lifetime warranty


  • Only 80 lumens
  • Straps can wear out over time

What Recent Buyers Report

Users comment on how bright these lights are, considering their size. They love the lightweight design, but some have noted that the rubber straps wear out over time. The manufacturer preemptively supplies a second pair of straps with your lights because of the rubber's wear and tear. The lights are durable, according to reviews. The units aren't bright enough for the day, but cyclists noted that the flashing functions make them more visible to traffic. 

Why it Stands Out to Us

These lights are an excellent choice. You can use them on your bike, helmet, backpack, or even pet. It comes with a lifetime warranty, which speaks to the manufacturer’s confidence in the product. 

The battery life is impressive considering its size. It's not the brightest lights on the market, but it’ll keep you safe on the road. It's ideal for use in well-lit or low-lit areas. The unit is practical and provides quality for what you pay. 

Bottom Line

You're not going to take the Vont Pyro bike lights on your next night trail ride, but for general commuting, it's perfect. The batteries charge for two hours until full, and you’ll get plenty of time between charges. It's a useful, versatile pair of lights.

Best Bike Lights Under $50:
EBUYFIRE Rechargeable Bike Light Set

EBUYFIRE USB Rechargeable Bike Light Set, 3000 Lumens Bike Headlight 3 LED【Upgrade Mount】,Super Bright Headlight Front Lights and Back Rear LED,3 Light Mode Fits All Bicycles, Mountain,Road


  • 3,000 lumens on the front light
  • All-weather safe and IPX5 certified
  • Made from military-grade material 
  • USB rechargeable batteries included
  • Three LED lights on the front and rear unit


  • Beam isn't focused
  • Mounting gives problems

What Recent Buyers Report

One user has stated that the light isn't as bright as advertised, but the consensus among buyers is that it’s perfect for city use. The mounting rack seems to be a problem, but you can buy a replacement from the manufacturer. Reviewers are happy with the length of time the batteries last and the various functions they can choose from, including an S.O.S. mode.

Why it Stands Out to Us

You wouldn't expect to pay under $50 for 3,000 lumens. The lights are practically indestructible with the military-grade material. The only flaw that this light has is the mounting rack that can crack. The manufacturer solved the problem by providing an upgrade to the standard frame. 

It's difficult to find any negative reviews about the light itself. 

Bottom Line

If you're on a budget, this light is the best choice you can make. Usually, you'll only get a front light with this many lumens for under $50, but with the EBUYFIRE, you get the front and rear light as a set. It's easy to install, charges quickly and will last a long time.

Best Rear Bike Light:
Canway Bike Tail Light

CANWAY Bike Tail Light, Ultra Bright Bike Light USB Rechargeable, LED Bicycle Rear Light, Waterproof Helmet Light, 5 Light Mode Headlights with Red & Blue for Cycling Safety Flashlight Light


  • Red and blue lights
  • 260-degree visibility
  • USB rechargeable batteries
  • Waterproof design for all-weather use
  • Rotational mount to change the direction of the light


  • Can be challenging to mount to your bike
  • Some states don't allow you to use blue tail lights

What Recent Buyers Report

There are almost no negative reviews about the functionality of this light. Users only have positive things to say about how long the units last, the brightness level, and the different functions. Make sure that you only use the blue light in states where it's legal, as it can get you in trouble, as one unfortunate user found out. The device is waterproof, and you can use it in all weather conditions, including rain and snow. Cyclists point out the light provides extra safety while out riding because it makes you visible for traffic with the extremely bright LEDs.

Why it Stands Out to Us

There aren't many blue lights available on the market. Blue lights tend to provide more safety than red lights because red is much lower on our visual spectrum and harder to see. Unfortunately, it's illegal in many areas. We like the fact that you can rotate the lights. It's versatile, and you can use it anywhere the clip will fit. 

If the blue light is illegal to use on the road in your area, you can always use it on your pet's collar or your backpack when you go hiking. The lights are ultra-bright, which is also not something you often find in tail lights. It’ll make you visible to any other road users during the day or at night.

Bottom Line

A tail light is an effective method of making sure you're visible to vehicles or other cyclists. Many tail lights are dim, but not these. Your friends may no longer want to ride behind you once you strap these units on your bike, fearing the loss of their vision. You won't easily find brighter tail lights for a better price.

Can Any Lights Be Used on Your Bike? What Bike Lights Do I Need?

You have to make the decision of which bike light you're going to use on your bike carefully. If your light isn't bright enough for the day, it's useless. Many lights aren't designed to withstand the impact of trail rides. Some states mandate how many lumens your light must have for nighttime use. Ensure that the light you choose will serve your cycling needs; otherwise, you're just wasting your money.

Types of Bicycle Lights

Let's take a look at the different types of lights to help make your decision a little easier.

Front Lights

Front lights can be used to see your surroundings. These are important when you're riding in poorly-lit areas, like trails or rural roads. Front lights can also function as visibility tools so that other road users can see you. The lumens in these types of lights don't have to be as high for nighttime riding but should be relatively high for daytime. You can look for lights with different beam settings, such as full and half beams.

Flashing Lights

Flashing lights are a popular way to make sure others can see you. You'll usually pair a solid beam at the front with a flashing light at the rear. 

Laser Lights

Laser lights will project an image onto the road to warn vehicles about your approach or intentions, adding to the safety equipment you already have.


Nothing is more important than your safety, but sometimes it's challenging to afford the necessary equipment. The lights on this list are all affordable and some of the best lights currently on the market. Make sure that you're safe and can see regardless of where you ride your bike.

People Also Ask

If you're still unsure which lights will suit your needs best, these questions that people often ask could be helpful.

How Many Lumens Should a Bike Light Be?

The lumens depend on when and where you ride. Daytime and poorly-lit areas will require higher lumens than riding at night in well-lit areas. 

How Many Lumens Do I Need to Ride a Bike at Night?

For nighttime cycling, you should look at lights with lumens between 20 and 100. If you're using rural roads or trails, you may need more than 100 lumens

Are LED Lights Allowed on Bikes?

Most bike lights are LEDs as they are bright and energy-efficient. 

How Much Do Bike Lights Cost?

Decent lights are always going to be more expensive. You can pay as little as $20 for good tail lights, and the prices vary according to the functionality. You can potentially pay up to $1,000 for some lights.

Why Do Cyclists Use Flashing Lights?

Flashing lights tend to grab other road users attention better than steady lights, especially during the day. 

Where Should I Put My Bike Lights?

You can decide where you want to use your bike lights. Generally, the front light is mounted between your handlebars. Your rear light can be under your seat, on your helmet, or your backpack.

How Do You Charge a Bike Light?
