Updated 8/30/17

Whether you’re a commuter or a cyclist looking to add some fun and fitness after work, bike lights are essential accessories. Their use doesn’t have to be reserved for after dark. Since 80% of cycling accidents occur during the day, adding lights to your daytime use is also a bright idea.

Fortunately the latest LED light are non obtrusive, fairly inexpensive and easy to use and recharge. Here are the best bicycle lights to see and be seen.

Characteristics of a great light:

Here are some of the main things to consider before choosing a head or tail light for your bike.

Durability

Does the light stand up to the elements? Taillights tend to collect more road spray, so ensure that the model is well constructed and waterproof. 

Optics

When you’re trying to distinguish shadows from potholes, the characteristics of the light cast matter. Things tend to look flat and undefined after dark, but a good light can help identify potential hazards. Beam patterns vary between models and a cast different light. 

Mount and ease of use 

How does the light attach to the bike and is it secure and easy to use? You want a mount that holds firmly and won’t slide or rotate on the bars as you adjust a setting or fumble for the power button.

If potential theft is an issue, consider how easy it is to pop the light off and carry it with you or consider picking up an anti-theft light such as the Fortified Bike Aviator and Afterburner Boost.

Finally, is it easy to adjust the settings through a pair of bike gloves or without taking your eyes off the road?

Battery life

There are a plethora of cheap bike lights out there. Many run on disposable batteries that can freeze or have a short life-span. Unless you’re only using a light occasionally, I suggest investing in a better model that’s rechargeable and has at least 4-6 hours of continuous use per charge. That may not seem like much, but when you divide your commute into chunks, it generally covers a week’s worth of riding.

Number of lumens

Companies can be misleading about the number of lumens a light contains. If you want to know exactly what you’re getting, look for a light with an FL-1 certification, which certifies that the number advertised is what the product contains.

How many lumens do you actually need?

Bike lights tend to range from 100 to over a 1,000 lumens. The lower end tends to be too weak, leaving a motorist hard pressed to identify a cyclist. On the other hand, the higher end can be eyeball-searing to drivers and should be reserved for mountain biking. The sweet spot is 300-500 lumens for cycling in a city and you can go a little higher if you’re riding solo on back roads.

We took all of these considerations in mind when choosing the best lights for the job.

1. Best Cheap Bike Lights for Commuting:

Light & Motion Urban 350

best bike light If you need to light up the night, the Urban 350 is a solid choice for the money. Four modes offer continuous light, flashing or both light and flashing, providing the ultimate way to see and be seen.

This light gets extra points for style, but it’s also very practical.

It casts 350 lumens for 1.5 hours, is FL-1 standard and charges via micro USB. A silicone mount fastens the light securely to the handlebars via an easily adjustable strap that can be swapped between bikes, no tools required. All of these features make it the best bike light for commuting. 

A rechargeable lithium ion battery makes this a great choice for easy charging. One of my favorite features is that the light also emits a bright amber glow for better side visibility. Check our full review of the Urban 350.

2. Best Bike Headlight for Day and Nighttime Use:

Cygolight Metro 400

Read our in-depth review of the Metro 400.

It offers more modes and a brighter light than the Light & Motion Urban 350 and features side illumination ports. It’s also USB rechargeable.

Cygolite Expilion 850

The Expilion runs for three hours on 425 lumens, making it a standout among other commuter lights.

On its Boost mode (850 lm) you’ll get an hour and fifteen minutes of light. It also offers a wide beam pattern to aid in lighting up your surroundings.

Another plus is that the battery pack can be swapped out for a freshly charged one. Riders with long commutes should consider this light for its infrequent charging. You can buy extra batteries on Amazon.

CatEye Reflex

best bike lights 2016Can’t remember to turn on your taillight? CatEye has a solution for that. The CatEye Reflex automatically turns on when it detects motion and darkness.

This saves some battery life and gives you one less thing to remember. The only downside is that the light isn’t rechargeable and is only activated at night, so daytime commuters will have to find another alternative.

11. Best Smart Lights:

Garmin Varia Smart Bike Lights (Head and Tail)

Garmin Varia If you’re after a light that you don’t have to think about, Garmin has a solution for that. The Varia headlight and tail light automatically brighten and dim to adjust to your surroundings and the headlight projects closer or further down the road depending on your speed.

The headlight will also dim its high beam for approaching cars. When the bike decelerates, the rear light responds to alert motorists of the cyclist’s presence. The remote control, also included in the package, offers an easy way to adjust lights on the fly.

If you’ve ever wished that your bike had a turn signal, Garmin covers that too. The Varia Rearview Radar alerts you to vehicles approaching from behind and can also act as a turn signal, working in conjunction with your cycling computer.

Note that these must be paired with a Garmin Edge and some of the more high tech features (like the light sensing auto-dim) are only compatible with the Edge 1000.
