Best Bike Lights of 2021 (Rear, Front & Helmet)

Best Bike Lights of 2021

Turning on your bicycle lights when the visibility is low is one of the most important things you can do to stay safe out on the roads. Check out our guide to front and rear bike lights as we explain all you need to know and share our recommendations.

In recent years, bicycle lights have become cheaper, more powerful, more durable, lighter, and more diverse. Therefore, the common excuses cyclists used in order not to carry lights are no longer valid.

If you’re thinking about purchasing a pair of bright lights for your bike, you might be confused with the huge selection available on the market.

Check out our guide below that will teach you all you need to know, as well as our recommendations for the best bike lights on the market.

Jump to Rear | Front | Sets | Night

 


Bike Lights Can Have Two Purposes

Not all bicycle lights are made the same. There are two main types you should know about when shopping:

  1. Making you visible
  2. Seeing in the dark

 

The first kind is the so-called “blinkers” and their purpose is to make you more visible to other drivers and riders. They are commonly mounted on the handlebar and the seat post and work in several blinking modes.

If you only ride in the city with well-lit streets, or you only ride in daylight and low light, blinkers will suffice.

However, if you ride in complete darkness or on roads without good street lights, it’s advisable to get a set of powerful front and rear lights that will make you seen and help you see as well.

Moreover, if you ride in the city, you can use a frame-attached bike flashlight. However, if you ride a mountain bike off-road at night, a helmet-attached flashlight is a must as well!

 

Front, Rear, or Both Lights?

Rear vs Front lbike lights Whenever possible, the answer is always BOTH. If you have a limited budget, a rear blinker is a good place to start. It will make you significantly more visible in low-light settings.

But being visible from the front is extremely important as well. Without a front blinker or a front light, you might be invisible to oncoming traffic which can be dangerous. Luckily, blinkers are usually bought in pairs.

However, if you’re buying a proper bicycle headlight, it’s a good idea to hunt for a set that includes a rear light as well, because you’ll pay less compared to buying both lights separately.

 

Number of Lumens Explained

Bicycle lights are usually measured in lumens, which is a unit that represents the light output of the setup. The more lumens your lights have, the brighter they will be.

This question is not simple to answer. It depends on where and how you ride. As a rule of thumb, if you ride in the city, on well-lit streets, a 400-500-lumen front and a 50-lumen bicycle tail light will get the job done.

Don’t believe “Chinese lumens”! Cheap bike lights from China usually have misleading lumen readings that overestimate the power output of the setup.

However, if you like going off the beaten path and ride on completely dark roads, you should get a pair of lights with more lumens. We recommend at least an 800-1,000+ lumen front light and a 50+ lumen rear light.

Many modern bicycle lights come with several power modes, so you can choose how bright you want them to be, depending on where you’re riding. This way, you can preserve battery life and make your lights more efficient.

 

Most Important Features to Look For

Lumens are important but they’re not the only metric that matters when buying bike lights. You should also consider some of the other features below:

  • Adjustable beam pattern: A feature that allows you to choose how wide or how far you want your lights to reach.
  • Multiple power settings: Changing the light output of the setup so it preserves battery life.
  • Sturdy attachment: You want an attachment that’s sturdy, stable, and won’t move around or fall off when you’re pedaling over bumpy surfaces.
  • Durable body: Bike lights are exposed to various types of impact. You want a set that’s has a strong and durable body that will not break the first time your bike tips over.
  • Intuitive battery indicator: Many modern best bicycle lights have flashing or beeping indicators that alert you when it is time to recharge your batteries.
  • Water-resistant housing: Ideally, look for an IPX water-resistance rating of five or higher that can withstand riding in wet conditions.

 

Handlebar or Helmet-Mounted Bike Lights?

Helmet bike light vs handlebar bike light

Most bike lights are mounted on the handlebar.

This is a good starting position, but it is no ideal for all situations.

Bicycle Guider TIP: If you’re riding on a trail on a mountain bike, you definitely need a light that points exactly where you look. The problem with handlebar lights is that they point where the bike is pointing. So, when cornering, you will have blind spots. Also, crossing bridges is quite risky, especially if they’re narrow or in poor condition.

helmet light will make this problem disappear. It’s even better if you use it in combination with a handlebar light. This way, you will eliminate all dark spots and see everything that’s in front of you at all times.

The problem is that there are not that many helmet lights available for sale in the US. You can find some Chinese bike lights on Aliexpress, but these usually come with some disadvantages.

FAQ

How many lumens do I need for a bike light?

The number of lumens depends on where you ride. If you ride on city streets, a 400-500-lumen front and a 50-lumen bicycle tail light will suffice. If you ride off-road, consider getting a set with an 800-1,000+ lumen front light and a 50+ lumen rear light.

Are LED lights good for bikes?

LED technology is the best choice for bicycle lights. LED bulbs are super bright but use a low amount of energy, so bike lights do not need large batteries to work for hours on one charge. Moreover, LED lights are reliable and last for a long time which is important for regular cyclists.

How do I choose a bike light?

When choosing the best bike light for your needs, you need to consider what type of riding you do the most. If you commute on city streets, a pair of blinkers will do the job well. However, if you ride on unlit streets and roads, make sure to get a powerful bike headlight and tail light.

How many lumens do I need to ride a bike at night?

If you want to ride a bike at night, on streets and roads that are not well-lit, you should get a bike headlight with at least 800-1,000 lumens and a tail light with 50+ lumens. With such lights, you will both see where you’re riding and make sure that others see you as well.

 

A Few Final Takeaways…

suggestedUsing a bike light is essential and there’s no debating about it. It is crucial when riding in the dark, but it’s a good idea to use it during the daytime as well.

If you still don’t have a bike headlight and a rear light on your bike, we urge you to invest in a pair straight away. Lights are the biggest and the cheapest safety upgrade you can make.

Hopefully, after reading our guide, you now have a better understanding of exactly what kind of bike lights you need for your type of riding.

Consider one of the front and rear lights or sets that we have recommended above to get the most bang for your buck and turn day into night.

  • Thank you for the reviews. I think Ascher is also a great helmet light. They make our bikes more visible from a distance both day and night. Rechargeable is great.

  • I’ve just gotten into the biking world from backpacking and have purchased a Rocky Mountain Growler. Went looking for a bike light and found this one that I really like. Anyone have any other suggestions? https://tonque.myshopify.com/

    • Editor says:

      Hi Richard,
      Looks good to me! Great for night riding. Check out the lumens. 500 lumens is good enough.

  • Robert Clark says:

    I bought IPSXP light to replace a 500 lm Axiom LED light that I lost the bike mount for. The duration was long-lasting, so I don’t need to charge it every day, plus, I don’t need to buy batteries anymore, I can charge it with USB (it is included in this item). Save me a lot of money from buying batteries.

    • Jeff Balton says:

      Hi Robert,

      Thanks for sharing your own experience with the brand! Yes batteries can be a hassle. Plus they are noit always the “green” way to ride the bike. Well, unless they are rechargeable.

    • VASTFIRE bike light works very well. Strong aluminum housing, super bright dual LED lights, that can be dimmed or flash as desired. It mounts on my flat and wide carbon fiber handlebar. It can be easily angled or turned to either left or right. The sturdy mounting bracket which doesn’t scratch your handlebar. Micro U charger is located at the bottom so that it minimizes any possible water intrusion from the rain.
