The brake light that could have been

The light I needed was for my new nightly ride. The light I got was good until my bike fell over and the plastic band snapped off. I don't blame knog for this but it was unfortunate that I had only a few days with it before date got a hold on it. What I will say is that the USB charging is good the light was strong and the settings were easy to navigate. I would buy another again just not right now

Compact and bright

Works very well on my recumbent trike! I have it attached to the seat stay.

Still getting used to it

My old rear light was simple to use and I couldn't remember when I last charged it... this one... so far, depending on settings... I've been charging it at least once a week?! YUCK. Again though, it's early days, and maybe I haven't found the optimum setting? OR maybe it'll get better with use?! Meh- it's a rear red flashy light that stays where you put it.

Red flashing light

I like the ability to use it in multiple locations, whether clipping on your shirt or clipping on your bike. I like the ability of the way it charges by simply just plugging it in to the receptacle no wires to use for charging.

Nice and bright, easy to mount

Very easy to mount and use, nice to be able to unhook it easily to use off the bike, or just so that it doesn't get stolen. Good brightness!

'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.
