On the road, bike lights are critical for our safety. Whether you need to see, be seen, or both, the best bike lights of today have come a long way from the lights of yesteryear.
There are so many bike lights on the market these days that choosing the right ones can be downright frustrating. With front and rear lights, lumens, beam patterns, light modes, and more, understanding exactly what you need is a challenge in itself.
To help, we rounded up our favorite bike lights and tested them for months. Our expert testers took evening grocery runs and early morning commutes and spent plenty of time riding dark bike paths, country lanes, and gravel roads to assess each model’s performance.
Below are our favorite bike lights for road, gravel, and commuting. If you’re a mountain biker, we have a full guide to the best mountain bike lights that will help you navigate singletrack long after sunset.
Editor’s note: This guide was updated on January 21, 2025, with the addition of the top-rated Knog Blinder 900, the impressive Outbound Lighting Detour, and the budget-friendly NiteRider Vmax+ 150.

Frequently Asked Questions
A car’s headlights put out around 700-1,300 lumens on average, according to the National Automobile Dealers Association. Most brands manufacture bike lights up to 1,200-1,800 lumens. The brightest bike light in our test group is the NiteRider Lumina 1800 Dual Beam at 1,800 lumens.
But a few brands make ultra-high lumen lamps for diehard night riders who need to light up the trails: CatEye makes the Volt6000, which tops out at roughly 6,000 lumens.
It depends on what kind of riding you’re doing and what you need the lights for. For daytime riding, the goal is to be seen by motorists, so there are lots lights on the market that aren’t particularly bright, but they still make you more visible.
If you need the light to see your way in low light or in complete darkness, you’ll want to get something brighter with a beam that illuminates the path ahead of you. For urban usage, you’re looking for something around 400 lumens or higher. The more well-lit the riding area is, the fewer lumens you need.
For riding in areas with no sources of artifical light, like bike paths and country roads, we think a bare minimum of 600 lumens is critical. Remember that most lights have multiple brightness settings, so you can always make a bright light dimmer, but not the other way around.
Warning: Over 700 lumens can be pretty hard to look at, so make sure you’re angling your light slightly downward if you have a bright light to avoid blinding fellow riders, pedestrians, or vehicles.
A few lumens are all you need to stay visible for rear lights. Many rear lights drop as low as 4 lumens, although 20 lumens or more is ideal. The Blackburn 2’Fer-XL has a 200-lumen white light and a 40-lumen red light. Our favorite rear light, the Garmin Varia, produces a respectable 65 lumens with a very solid 6-hour runtime.
Unless you’re simply looking for a blinking rear light for the occasional commute, a rechargeable bike light is superior to a battery-powered option. Rechargeable lights might cost more initially but after just a couple of battery charges, the cost will balance out.
The Sierra Club notes that rechargeable options are more eco-friendly, as they avoid constantly disposing of used batteries.
It depends on how much you ride in the dark. A full bike light set is optimal if you find yourself regularly riding at night, at dawn or dusk, or in bad weather conditions. Many brand sell front and rear lights in bundles, though it is perfectly suitable to mix and match between front and rear lights of different brands or models.
Studies have confirmed that bike lights do help make drivers notice cyclists. The National Highway Traffic Safety Administration has found that the highest incidence of cyclist fatalities happens between 6 p.m. and 9 p.m.
If you live in a well-lit area and rarely venture out on the bike in the dark, a rear light (and perhaps a headlamp for the occasional short night commute) may be plenty. The rear light is critical for making yourself visible to cars coming up behind you.
A front light can also help you stay visible to cars that might be veering off course, as well as to pedestrians who may run or walk opposite the flow of traffic. It can also keep you from crashing on the road. Legally, you might be obligated to have both.
During the day, very few places will require that you have a bike light, but at night, most cities and states have some requirements for visibility. You’ll want to check your local bylaws. Certain states require not just a small red rear light on your seat post, but a full light set.
The reality is, if you’re riding a bike in the dark, front and rear lights are critical for your safety. So, even if you can ride legally without them, you probably shouldn’t.
You should also run your rear light during the day, and possibly even a front light when the weather is poor. A Clemson University study found that cars were much more likely to spot cyclists who were using lights during the day, as well as at night.
While you can use a headlamp as a bike light, the area and distance you need to illuminate while biking may not be quite the same as the lighting you need for hiking or running in the dark. That said, a headlamp can be a great addition to a bike lighting setup, especially for night-riding mountain bikers who want to scan the trail.
You can use the headlamp to scan from right to left ahead of you while keeping your trail directly ahead lit up with your handlebar-mounted light. For which headlamp to choose, check out our Best Headlamps Round-Up.
Even then, serious mountain bikers will typically opt for a helmet-mounted bike light that is purpose-built for the application.
