Useful addtitional visibility

Not for use as a main rear light but a useful supplement. I use one as a side light by putting it on my rear forks facing outwards. Easy to get on and off.

Rear Lights Buying Guide


Rear Lights Buying Guide

While front lights can reach up to and above 1000 Lumens, at the rear anything from 20 to 100 lumens is plenty. Multiple rear lights are the best way to be seen from behind, especially when on the flash mode.

With one attached to the seatpost it can be good to have another on the chainstay, backpack or helmet. 20 Lumen would be sufficient for commuting in urban areas. For those living in darker areas or riding on dimly lit roads, a rear light closer to 100 lumens would be best.

Take a look at our Rear light comparison tool to help you choose the right bike light for your needs.

Wearable lights

Extra visibility

If you commute on lit-up city streets, rear lights are more than essential. To have a second light high up and in the eye-line of drivers and other road users is a very good idea. With reflective clothing and/or accessories like backpack covers and jackets, adding a wearable rear light will really make you stand out. Most backpacks will have a loop or somewhere to secure a light, using the strap or mount that come with the light.

Usually not a concern for MTB riders, nothing extravagant is needed for the rear, just so the rider can be seen on any road or path that might lead to the trail.
