Knog's Frog series lights are the original "itty bitty silicone lights", designed to wrap around the handlebars for quick removal. These lights are best used as a backup light just in case you get stuck out at night — they're not designed to light up the path and likely aren't bright enough for frequent night time rides. They are cheap, portable, and easy to use though, making them a good choice for a light to keep in your bag just in case for when you aren't expecting to be out at night.

Review: Too dim for regular use, but useful in a pinch after dark

Review by , Sept. 12, 2013, midnight

The Knog Frog light is small, easy to quickly strap on your handlebars, and easy to keep in a bag just in case you need it. However, it's not bright at all — it's really only usable as a be-seen light, if even. The CR2032 batteries it uses cost almost as much as the light itself. For the rider who rarely goes out at night and wants to have something in their bag just in case it gets dark, the Frog is useful, but for serious night riding a brighter light is in order.
