Knog Plus Clip-On Bike Light: LED, Waterproof, Universal Mount Bicycle/Running Light

I went ahead and purchased this product based on mixed reviews, a few people state that one of the lights arrive faulty. Upon opening the Amazon packaging, the red light was flashing away and showed a low battery warning indicator (single led light below on/off button) , I placed both the white and red light on charge (plugs directly into USB slot) and then proceeded to try the lights when fully charged (Charging light turns off when complete, approx 4 hours for a full charge). The red one worked well, it was very bright and worked well on all the different light settings. The white light failed to turn on and after numerous attempts I managed to get it to work for a few seconds, before it turned off again! I've ordered a replacement as the design seems very good. Hopefully both the red and white light will work and I won't have the inconvenience of returning a second set!

I like these lights as they are light and versatile. However they both didn’t last very long. 5 months into their life and they are both not longer working as intended. As you can see from the photos attached both lights are constantly on and cannot be switched off at all. This obviously drains the battery life and the lights needs replacing. Good thing the lights are covered by a two year warranty and I should be able to get them replaced. Would I recommend them? Well yes .. good warranty and versatile lights.. it may have been just a faulty set!

The best thing about this product is how discreet the lights are. Super easy to install, easy to disconnect and charge. 10/10 for design and usability. I've had a problem with the rear light not working as it should, however I have a replacement being sent.Fantastic service - overall 9/10 due to faulty rear.

Good, visible light but sorry knog, battery life is half that advertised. Pulse mode will do less than 2 hours vs 4.5 hours stated on the website. I've used other knog lights in the past but this one's a fail.

Powerful little lights. I use these on my electric scooter. One strapped to the upright column and the other clipped to my backback. They give off substantial light and have a variety of flash modes.

Easy to attach on bike and easy to charge. Many settings available and the lights are very bright!

Very neat units

Waste of money, used them about 5 times, first of all the rear light stopped charging then very soon after the front stopped working.
