Bike lights are increasingly becoming a very important piece of accessories to have especially when it comes to safety. They serve 2 purposes; for you to see and be seen.

With so many models in the market today to choose from, it doesn’t come as a surprise that the most commonly asked question among cyclist is;

  • Which is the best bike lights to buy?
  • How many lumens do I need?

There are many things to consider such as the brightness levels, the number of light modes, battery life and more. 

How We Pick Bike Helmets

We start by thoroughly researching all the bike lights for sale at the largest stores such as Competitive Cyclist, Jenson USA, Wiggle, Chain Reaction Cycles, and Amazon. Then, we trimmed down to only those with more than 50 positive reviews and an average user rating higher than four out of five stars.

Since we began publishing this guide a few years ago, we’ve always kept an eye for newly launched products and are in constant contact with the manufacturers through direct contact, meeting up at bike expos (pre-COVID), and scouring press releases.

In making our picks for bike lights, we focus on the objective criteria below :

  • Price points. Lights can cost anywhere from $20 up to $200. The more features, the higher the price. Our budget picks are between $50 to $70 and smart light picks usually range from $150+.
  • Brightness. The brightness you need depends on where and when you ride. We picked daytime riding lights that are much smaller, compact, and between 50 to 100 lumens. If you do mountain biking at night, you’ll need at least 1,200+ lumens. The sweet spot for road cycling (day and night) is between 400 to 800 lumens.
  • USB Rechargeable lights make it more convenient and environmentally friendly. You can forget about disposable batteries.
  • LED Bulbs. There is a general consensus that LED bulbs last longer and is way more energy efficient than traditional bulbs. 
  • Mounting Types. All our picks are known for their sturdy mounting on the handlebars. Depending on the models, they can be mounted either on top or in front of the handlebars. Some models can be mounted below the bike computer for a cleaner look.

I covered these in detail in our bike lights buying guide.

Frequently Asked Questions

In the preceding section, I tried to cover as much as possible, but there are a few particularly common questions cyclists have about bike lights.

I’ll address them below.

How many lumens do I need for road cycling?

The ideal brightness for a bike light is between 300 to 600 lumens. The Knog PWR Road and Lezyne Micro Drive 600XL fall into this category.

If you’re riding mostly along unlit bike paths, then you can go up to 800 lumens such as the Exposure Lights Sirius.

As I’ve mentioned above, you don’t need the highest lumens for 2 very simple reasons. If you’re riding on the road, you could risk blinding the oncoming cars.

Secondly, running on the brightest mode will significantly shorten the battery life.

Is it illegal to ride without lights at night?

Depending on where you’re located, it can be against the law to ride your bike without lights at night.

There are local bike laws in every state in the U.S. that regulates how bicycle lights are used. There are also similar laws in the U.K. and Germany.

While each state might have a subtle difference between them, it’s generally accepted that you should have both active and passive lighting on your bike.

For safety and visibility purposes, I strongly recommend you to use one.

What are CREE LED?

CREE LED lights are manufactured by an American company, CREE who is the industry leader in LED lighting.

It was started back in 1987 in North Carolina. Today, CREE manufactures top-quality lights and they are widely used indoor, outdoors, and in LED lights.

Lights such as the NiteRider Lumina 1100Exposure Lights Sirius, and Light and Motion Urban 650 uses CREE LED.
