How to Find the Best Mountain Bike Lights

If you’re serious about cycling then you should definitely invest in good quality accessories such as a bike helmet and mounted bike light.

This will keep you safe when cycling in low light conditions, whether that’s during twilight or fog.

However, you might still feel confused as to what exactly constitutes the best mountain bike lights for night riding.

To help narrow down your options further, check out the following considerations:


The lumen is an indicator of how bright your bike light can get.

300 to 500 lumens is the best category to use if you plan on using your road bike to commune, whereas off-road cycling requires something a bit more sophisticated such as an LED technology bike light with 1000 lumens or more.

In addition to the brightness, the width of the light beam is just as important because you want a wide field of view.

You can also go through my extensive guide to the best bike headlights for knowing more about its desirable features.


Most bike lights come with either AA or AAA batteries. But some models are powered by a USB rechargeable battery which means you can recharge it using a USB port.

Most back-mounted headlights use a lithium-polymer battery pack, which is small, lithe and slim.

The most important thing here is to make sure the light is powered by a durable battery whose power can last and last.


Headlights are the most popular type of light and can be mounted on either a handlebar or straight onto the MTB helmet.

An off-road biker who wants to get into dirt biking should definitely consider a handlebar or helmet-mounted light for simplicity and safety.

But, you may also opt for tail lights which are also known as rear lights.

They’re designed to improve biker visibility among car drivers on the road, and can be mounted on the seat post. The best kind are lights that are a combination of the rear and headlight.

You can read my article about the best bike tail lights to learn more about them in detail.


As you start shopping for bike lights and exploring different models, you’ll see that different brands offer different types of lighting modes.

For best results, opt for a bike light with up to five lighting modes or at least an ability to increase or decrease brightness to suit your surroundings.

A good quality MTB light should also come with some type of pulsating light or flashing light mechanism to improve visibility.


Your light and your helmet rear view mirror should fit properly and be easy to attach and detach when necessary.

My article on bike helmet rearview mirrors will guide you through the importance of this essential accessory.

If you’re a mountain bike rider, then you’ll do well to adapt to both kinds of mounted bike light, i.e., the traditional handlebar mount and the helmet mount.


It’s advisable to opt for a lightweight cycling headlight that’s comfortable to wear and easy to use no matter how short or long the distances you travel.
