Best Bike Lights you can get

long-lasting, bright light, easy to install and beautiful to look at. my 2 pairs, I am very satisfied!

Andrew Foulkes
Light up day and night.

I’ve had big cobbler lights for a few years now and would recommend them. During the day I have them on a dim flash. At night bright flash. The battery lasts a reasonable length of time. Easy to swap over to my other bikes.

Perry Pollino
Safety matters.

I thing these lights are the "Cats Meow"

Ryan Hadley
Top Notch Equipment!

I love these lights, I swear you could see my bike from space at night when I have both of them going. People always compliment how they look and I always recommend that they check em out! I love them for visibility on the road and I feel safe when I have them on.

Love the brightness and they fit perfect on front forks and seat post. Easy to customise patterns/speed and brightness. My favourite knog lights to date
