When the fog is out, Knog is the best

Actually bought these rear bike lights primarily for running at night. Brightness, durability and compactness surpassed by none.

Love this light!

This is my second plus rear light since the button on my last one tore off, but truly that was my own fault for keeping it in my Ortlieb bag with my heavy bike tools. Otherwise, I love the simplicity of how this light charges, how portable and bright it is, and the price. Remember to hold the button down to power on the light. The packaging doesn't say to hold the button down to power it on, but the online user manual does.

Man, what a light, very bright!

Awesome rear light with many modes more or less energy saving depending on the brightness. Very slim, looks perfect for those narrow aero seat posts, even though the longest elastic band is "limit short" for a Canyon Aeroad seat post.

Versatile rear light.

This light is bright and versatile. I attach to the frame using the strong bands and it also slides nicely on to strapping on my pack pack.

真係好光,望一眼都好刺眼。

'a beautiful and functional design, coupled with purpose and power.'

‘4.5 / 5 Stars. Knog Plus lights attach easily and unobtrusively to the bike. But they can also be worn on clothing, making them very versatile... and the run time is good for such a compact unit.’

Knog's Most Versatile Light Ever.

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

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 plugs directly into USB-A ports & is designed to be exposed to the elements. Just remove from it’s magnetic mount and you’re ready to charge.

Charge Indicators

When Plus 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.

Mount It Or Wear It

Mount on the seat post, seat stay... anything goes. Or remove from the mount and it now doubles as a wearable running light or versatile camping light.
