Great little light.

Clip it on the back of your helmet and Stevie Wonder could probably see you.

Almost perfect

Very light and durable, easy to turn on/off, good battery life in blinking mode. My only regret => does not to have a hole or any type of hold to add a tiny leash on and avoid losing it while I bike

Just perfect

Perfect thing, perfect device, perfect choice.

No Complaints - Wearable Plus Free Rear Light

So far this light gets an A+ from me. Super bright. Easy to clip onto a number of things on my backpack. Charge seems long lasting. Very minimal design but super visible with multiple flash modes. Another great value from Knog!

Fantastic light! Very bright and holds a long charge!

'light up the night & be seen by other road users.'

‘If you like to run, walk, ride or camp – anything outdoors at night, really, this product is ideal. We highly recommend the small investment!’

Adventure Mag

It's An Impressive Wearable Light.

Simple, effective and packed with features that make it a pleasure to wear.

Latest COB Technology

Efficient Chip on Board (COB) LEDs provide maximum brightness level for up to 90% of the battery burn time.

Integrated USB Connector

Plus Free plugs directly into USB-A ports & is designed to be exposed to the elements.

Wearable Clip

Use the clip to attach the light to your hat, shirt, shorts, socks, headband, backpack, dog collar (we could go on).

Charge Indicators

When Plus Free is running low on battery, a red ring will light up around the button. This ring will also show when charging, and turn off once fully charged.
