Just buy separately

I’m returning and buying the big cobbler rear light as a standalone. The front makes you visible, but does nothing to light the road since it’s so disbursed. For the same price as a big cobbler front, I’ll buy a PWR light that both keeps me visible and actually lights the road in front of my bike. I give the rear 5/5 for both brightness and visibility, but front is a 1/5 for usability so I split the difference.

Hey Ryan, firstly, thank you for sticking with Knog! You're right of course, Cobber front lights are in our 'Be Seen' category, great for attracting attention day & night in urban environments where street lighting etc lights your path ahead. If you're looking to light up dark roads / trails, a Knog 'See By' light is the way to go. If you can't find a PWR front light (they've been discontinued), we've just launched a new Blinder collection (June '23) which comes with 600, 900 & 1300 lumen options. All the best!

Awesome lights

I started commuting by bike sixteen years ago and I’ve gone through a lot of lights and these, so far, are the best lights I’ve used.

Great bike light

Just used on a 120 mi ride and these lights worked the entire time longer than the stated durations.

Really Cool

I really liked these lights but I only got to use them for a week before my bike got stolen with the lights on it (._.)
Super bright and awesome light modes, I'd fersuree buy these again.
