What to Consider for the Best Mountain Bike Lights?

Battery Life

In reality, not many people go night riding. However, you may find yourself in a situation where that has to happen.

For that, you’ll need a commuter bike helmet light with a good battery life that can last for at least 6 hours of non-stop use.

If the battery is interchangeable, the better for you as you can carry an extra one for emergencies. Lithium-ion batteries are the most reliable.

Dual Lights

Dual lights are always a better bet. The ability to light both ways is safer than what many people imagine it to be.

Having one front light focused ahead and another dealing with the back also serves to notify others of your presence, helping you prevent injuries while on the road.

Weight

The smaller the light, the better it is for your general comfort. The last thing you’d need is to add extra weight to your head strap as this will become cumbersome and could affect your ability to judge the distance well at night.

Fortunately, many are small in size, but you’d be well placed to avoid the heavy ones if you can.

Brightness

The brighter the bike helmet front light, the better it is for the safety of the cyclist. Dim lights aren’t a good idea as they’ll force you to strain your eyes too hard; this could lead to accidents.

At the same time, using lights that are too bright is dangerous for other users as it may blind them, and that could turn tragic, especially where oncoming cars are involved.

Light Modes

The best bike helmet light isn’t a sophisticated device, most come with single buttons for switching them on and on. To be able to control them, you’ll need the types that have different light modes.

Light power modes give you the ability to choose the light’s intensity depending on the prevailing conditions. On the minimum, please don’t settle for anything with less than 3 different light modes; the more of them, the better.

The Bottom Line

As already mentioned, you may never need to use your bike at night, and if you do, there are street lights everywhere these days, but it’s always better to be ready for anything. Make sure you carry your best bike helmet light with you even when the distance involved is short.

All the light types mentioned in passing here are just the tip of the iceberg. The market is flooded with helmet lights of all shapes, brands, and designs; finding the right one can be a headache.

This guide is here to give you a hint on where to start and what to look for.
