7 Best Bike Light Sets on Amazon

The most important test for me is whether am I being seen and whether I can see sufficiently. I ride the same route at similar times and conditions to allow for a consistent traffic flow to give a good baseline. This includes town/city riding along with some quieter lanes and tracks. The front 600XL uses a permanently attached rubber strap to wrap it tightly around the handlebar but it also rotates on the clamp allowing you to fit on a fork leg or any odd angled position. Despite being used on the fork leg for long distance riding, we had no issues with the light remaining steadfastly in place.

It only accommodates round posts and requires a screwdriver for mounting and unmounting. That said, it is quite easy to slide the light off the mount without having to remove the mount itself, so you can clip this onto a backpack or slide the light into your pocket. While there are some smaller lights built into the sides of the Varia RTL515 light, they aren’t as prominent as other lights in the test. It’s great that the lights are integrated into the radar in the first place, but they definitely don’t seem to be the primary function here.

Some lights will reduce their output as the battery begins to run down to extend battery life. Any bike light in this list is worth considering and many options will suit your specific needs. Each has an ambient light sensor to adjust brightness and you can hook them up via ANT+ with a Garmin cycle computer for auto-on when you start to ride and to swap between modes. The setup is fiddly for the alloy mount and the beam patterns, which you select with the light off, meaning you have to go through the process again if you don’t like the result.

If you’re using your bike light as intended—that is, moving forward and thus generating airflow—this shouldn’t happen often. And if you do stop long enough to trigger that “overheat protection” mode, the light should power back up to normal once you start moving again. The main reason this headlight isn’t our top pick is that it’s just too bright for your average urban commuter, whose ride will be at least partially illuminated by street lights. Those riders will inevitably be sharing their routes with others (drivers, bikers, pedestrians) who also need to see the road in front of them. So a 1,000-lumen light can be potentially blinding and therefore just plain dangerous.

The bike light that’s right for you depends on such factors as where you ride, when you ride and what you ride. What I love about this light is that it’s both a killer front light that easily attaches to your handlebars, and a helmet light that attaches to via a helmet mount. I also love that it comes in various degrees of power, so if you don’t need (or don’t want to pay for) an impressive 1,100 lumens, the same light is offered in 100, 200, 400 and 500 lumen options. The push-button activated setup attaches to most spoke styles and the battery runs for about six hours before it needs a charge via USB (cable not included). Choose between red, green, blue, purple, yellow and white settings, or opt for the Disc-O mode and light up the night with flashing rainbows. Mountain bike lights often come with a larger, separate power pack that straps to a top tube, or fits in a frame bag for gravel, to save mounting a giant ingot to the bars.

The 1200 OLED Boost’s mount is actually better though; it can be adjusted easily using the thumb-twist screw, and you can remove the light entirely from the mount to charge it, or use it as a flashlight. The Light and Motion Vis Pro 1000 Trail is incredibly simple to operate and plenty powerful enough with a reliable mounting bracket and lightweight build. The Cycliq Fly12 Sport is a bright and reliable bike light and video camera, all in one package, making it a great option for urban cyclists looking for peace of mind. Larger lights typically use solid plastic or metal mounting systems, which clip onto your bike or are secured with bolts. A greater runtime will typically mean a larger battery and therefore a larger light. If you’re using lights for commuting, you may want a smaller light to stuff into your bag, but you may have bike lights to charge it more often.

Brightness and Lumens

Still, I do think aesthetics are a secondary consideration to how well it actually lights. The Vis Pro 1000 Blacktop is best if you’re looking for a powerful light and want to save a few grams. But if you’re after a wide beam, long run time, or easy removal from the mount, look elsewhere.

The Knog PWR Trail 1100L bike headlight additionally functions as an effective flashlight, power bank and lattern. For the most part, lights designed for commuting will be smaller and less bright, though with newer designs that generalization is starting to vanish. The biggest difference is that lights used on trails will need to be very bright for a longer amount of time, and the beam pattern may be considerably different. The Micro 900 is a simple light that packs a lot of great features into a compact design. On a mountain bike, the Micro 900 should be combined with another light, either bar- or helmet-mounted.

His cycling pursuits have taken him to destinations across the U.S. and Europe, Taiwan, Costa Rica, Israel, and beyond. He has stood on the podium at several cyclocross national championships, and is a silver medalist at master’s cyclocross worlds. Today he guides adventurous gravel cycling and bikepacking tours through his company, Alter Exploration. Though the Cygolite is intended for commuter use, we found the clamp is strong enough to survive bumping and jostling over rocks and roots during mountain bike rides, too. And after accidentally sending it through the wash, we can vouch for its water resistance.

The rubber mount is best suited to people who ride the same bike every day. Although the City Rover 700’s rubber mounting strap stays put over rough terrain, it takes far more hand strength to tighten it around your handlebars; this is frustrating in very cold or wet weather. The quick-release latch makes it easy to remove the light itself for charging. But if you’re planning to swap this light between bikes, you may prefer our top pick.
