I have always loved KNOG products and absolutely fell for this little twin pack that I gifted to a friend when they finally got their bike up and running ... Only now I'm rather jealous that I didn't keep them for myself!!
Good battery and visability
Lil Cobber Bike Light Twinpack
Haven’t skipped a beat in 3 years. Great lights
I use these on my Brompton as there isn't a lot of space for other kinds of lighting. Lights are as bright as expected and easy to take on and off my bike.
Only complaint, and it's a minor one is that the usb recharging tabs on these don't fit in all of my various chargers. But they definitely fit in most.
