Can you really still be bothered with bike lights that constantly need their batteries replacing? What a huge waste of your precious time and money.
Why bother with all that hassle when you could simply buy a USB charging bike light? They take up precious little space, are very light, they are generally easy to clip on and off the front and back of your bike and you can easily pop ‘em in your pocket.
Not only this, but they can also be charged on the go – unlike bike lights requiring batteries, obviously – and are as safe and secure as any other light for cycling.
Regardless of the weather conditions you’re cycling in, these bike lights will do their best to prevent the risk of potential accidents, and eliminate the unnecessary worry of whether they will suddenly run out of power at any given moment.
How Bright Should Bike Lights Be?
It really depends on the type of bicycle and the type of cycling you’re doing. As a general rule:
- To be seen in daylight: 100+ Lumens
- Urban commuting lights: 50 to 200 Lumens
- Rural lights to see where you’re going: 400 to 600 Lumens
- To see everything: 600+ Lumens
Before committing to a bike light, it’s also worth double-checking their brightnesses. They may advertise themselves as a 900-Lumen light, but may only be able to work at 900 Lumens for, say, 30 to 60 minutes. Read the small print.
And of course, it’s important to be lit at both the front and the rear, because you want to see and be seen. But especially at the front, because it takes more power to help you see where you’re going than it does just to keep you visible.

USB Bike Lights – FAQs
How long do LED Bike lights last?
It’s really hard to say because it depends entirely on which light you buy and on what setting you use it.
If you go full-blast straight from the offset, then rechargeable LED bike lights could last as little as two hours before needing a recharge. If you’re more conservative, you could probably get at least three whole days’ worth out of them.
How to charge USB bike lights?
If you buy a bike light with USB charger included, just plug the small end of the USB cable into the device’s USB port, and the large end into an AC adapter or computer USB port.
If it’s an AC adapter, then it will need plugging into the wall, then, but once you’ve done that, you should be good to go.
Where to put bike lights?
On the front on the rear of your bike.
More specifically, though, put the front light roughly halfway between your two handlebars, and the rear light just underneath your saddle.
Keep them parallel to the ground so that you get the biggest visible range and make you the most visible you can be to other pedestrians and drivers.
