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
Not received yet
The lights do not charge I contacted you and they never got back to me and finally PayPal gave me the money back piss off
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.
