Customer Reviews
A nice improvement on the old frogs and other small Kong lights. A great set to have on the bike to be seen in low light when your ride went longer than planned
Buyer beware, these lights ship from Amazon. Thought I was supporting a small, independent business. Instead I gave my money to the devil. What a bummer.
If the og knog lights bring back fond memories for you, you will love these. Brighter than before. I will buy again when I eventually lose one.
Being spammed to make a review of a product I haven't had time to use yet. So here it is.
The bike lights for everywhere. in case you find yourself changing between different bicycles you will find situations where you have always to make sure you have enough light on your bikes. Knog Frog fits in you pockets and is always easily mounted on your current bike.
