Have used these lights for about 2 weeks and already could say that there is a massive improvement in visibility in both day and night. With multiple light modes and an app for your computer to fully customize your light settings this purchase was well worth the price

Big Cobber Bike Light Twinpack

The cobber model was my first introduction to Knog, and the best bike lights I've ever use, better than my old bike lights and won't be trying out anymore bike lights ever again, Knog will be my bike lights to go to forever.

Front light very bright for being noticed.

Don't know why there isn't a wider clasp for mounting. A number of comments on Amazon site mentioning this!

Definitely be seen, not see category

These are amazing. As the title says, they're super visible. Slightly worried about blinding pedestrians at night.. Being able to set your modes via the application is great though, ended up with just three modes I really liked. Mix of ones for use in traffic and for bikeways etc
