Best Bicycle Helmet Light

Written by: Dave NartinFebruary 28, 2020Updated: March 4, 2020

A helmet light is an essential piece of equipment for every rider. It is arguably one of the most important things necessary when riding a bicycle, right next to a helmet. If you’re fond of riding outside until the sun sets or if you like riding your bike at night time, then you should always have a light with you.

Unlike other pieces of protective gear, helmet lights are meant to prevent disaster rather than reduce the impact of one. These will help you navigate through dark areas but more importantly, they’ll make other people on the road aware of your presence. 

Here’s a short guide on how to pick a good bike helmet light as well as the best ones you can get.

What to Look for in a Bike Helmet Light

Brightness

This is first thing you should look for in a bike helmet light, but keep in mind that brighter isn’t exactly better. Light intensity is measured in lumens, and the amount that you need mostly depends on your location. 

For well-lit cities, 200 lumens should be enough to offer enough light for the occasional dark street or alleyway. On the other hand, off-road or mountain trails will require lights that are over 1000 lumens bright to ensure maximum illumination. Very high lumen ratings are best used for pitch-black environments for obvious reasons, while low-intensity lights are better for urban environments; they’re bright enough to offer good visibility while keeping other motorists on the road from being blinded. 

Compatibility

Helmet lights are generally made to be compatible with most types of helmets, but there are some that may not fit the helmet you own. Be sure to check out if a mounted torch can be installed on your helmet before you get one. 

Additionally, some bike helmet lights come with handlebar mounts as an alternative mount location. They essentially work the same way as headlights in other vehicles do. Mounting lights on your handlebar may be more favorable in some situations but if you’re creative and really want a helmet light, don’t be afraid to try out alternative solutions to make sure any light that you have won’t go to waste. 

Battery Life

The battery life of a helmet light should be able to last a few dozen hours’ worth of run time, or as long as your usual trips would require. There is no standard duration for a helmet light’s battery, but anything that can last for over 12 hours should suffice. 

If you’re the type of person who loves biking at night, then a long-lasting battery is best. When looking for a light that can last an entire night, look for its milliamp hour (mAh) rating. High-mAh batteries will last longer than ones with lower ratings, assuming the brightness output is constant.

Durability

Another thing you’ll need to look for in a helmet light is durability. Your light should be able to withstand drops from significant heights without cracking its chassis or damaging its internal components, but you should also be aware of any dust or water-proofing that a light may have. These features will be especially useful when riding on dusty dirt roads or during the rainy season.

You should also be aware of the durability of your helmet light’s mount. After all, your light won’t be of much use if it falls off while you’re cycling. Take note of the type of straps that secure your light to your helmet or handlebars. If you feel like they aren’t as secure as you would like them to be, feel free to try out some homemade solutions. 

Types of Bike Helmet Lights

There are two main types of bike helmet lights: high-output lights and safety lights. The difference between them lies in their brightness level.

High-output lights, as the name suggests, have very high lumen ratings. These can easily reach 1000 lumens and are perfect for off-road or trail biking. They are also much more useful in low visibility conditions.

Safety lights, on the other hand, are more suited for urban environments where you can rely on other light sources for navigation. Safety lights are used for alerting other motorists of your position in order to prevent roadside accidents. 

Be sure to pick a light that suits your needs. There are some high-output lights that come with safety lights but you can also consider getting a dedicated taillight to your bike instead.

NiteRider - Rechargeable MTB Road Commuter LED Bike Light

NiteRider – Rechargeable MTB Road Commuter LED Bike Light

Why it's better?

  • The Lumino Micro’s 750 lumen rating is strong enough for dark off-road environments without being too bright for urban areas, considering that the usual lumen rating for a low-beam car or motorcycle headlight is about 700 lumens. Its ability to adjust its light strength with five settings also gives this bike helmet light great versatility in multiple environments.
  • In addition to its optimal lumen rating, the Lumino Micro’s design is superior in terms of durability and functionality. It’s easy to install on any helmet light mount or on the frame your bike, and its solid construction with the DuPont fiberglass reinforcement makes it a great light to take when riding out onto rugged terrain.
  • Its Lock feature helps regulate its battery consumption, and its heat sink also helps it maintain its longevity.
  • Contributing to its ease of use, it’s also rechargeable and eliminates the need to change batteries.

The TANSOREN Bike Headlight is a military-grade bike helmet light with an extremely bright LED that can last for a surprising amount of time. It is very versatile and you’re going to have to try very hard if you want to break this one. 

This helmet light is very easy to install on your bike or a helmet light mount, and it’s also remarkably small and lightweight despite its sheer output strength. It’s made out of waterproof, military-grade plastic that’s enough to withstand any type of accident that might happen during a trip. 

The TANSOREN bike light uses two LED lights powered by an 18650 battery pack to produce its signature bright light. The light has four different modes: high, low, middle, and strobe so you can adapt according to your environment and to make sure you aren’t unnecessarily wasting battery power. The short wires that connect the light and the battery make it a little hard to mount, but it’s doable. 

This bike helmet light can last for 6-8 hours depending on the brightness setting, which is rather impressive considering that it can emit a light that’s almost four times stronger than other bike lights. It might be a bit excessive to some, but it certainly has its uses. Overall, it’s a great choice for its durability alone but if you want something that can really light your way, then you can’t go wrong with the TANSOREN bike light.

The NiteRider Lumina Micro 750 is a high-output bike light with excellent form and function. The Lumina Micro 750’s housing is made of a sturdy nylon reinforced with DuPont fiberglass, making it incredibly tough and impact-resistant. This paired with its innate IP64 water and dust resistance makes it one of the most durable bike lights in the market today.

The light has a 750 maximum lumen brightness level ideal for areas with very few light sources, with five light modes for versatility. It also has a Lock feature that keeps the light turned off when it’s not being used to ensure that precious battery life isn’t unnecessarily used up. In addition, it has a unique aluminum heat sink fitted into its design to allow for efficient heat dissipation, greatly reducing the risk of its internal components being damaged.

Speaking of battery, the Lumina Micro has a low-battery indicator that alerts you know when it needs to get recharged. The indicator goes off when the battery reaches about 20% of its max capacity, which is still plenty of juice to get you home in case the battery dips to critical level. Just be careful since this feature can actually end up draining the battery instead of preserving its charge.
