The Ultimate Guide To Choosing Best Bike Lights In 2021

Before you come to the final decision, there are something you might want to take into consideration:

Battery

Long battery will be a good point when you want to take a bike light for commuting or tour. Most of the time, the long flashlight battery life means the better system operation. And the current bike lights will normally have the fuel indicator. So, let’s make a right judgement.

Mounting system

If a bike light makes you feel hard to install or attach to the handlebars, I would recommend you to change. Basically, you could mount to handlebars or helmet. But there are some popular brands supporting both and that would be convenient for any riders.

Regarding tail light, you can check if it would be compatible with multiple places: seat post, helmet or your backpack.

Brightness: Lumens

How much lumens per led would define how bright your light is. It is much more important for headlight or front lights to have more lumens. Front lights should have more than 10 lumens and sometimes it can reach hundreds of lumens to offer the superb brightness.

You should care for lighting modes if they can be flexibly switched.

Durability

Commuters or cyclists will surely cope with the unpredictable weather conditions. So, a durable light would be a help. They will need a water and dust resistant light to go with during a difficult situation. It also defines the lifespan of your lights. So just be careful to get your own light.
