Review on Cygolite Dice HL – 150 Lumen Bike Light: Compact, Water Resistant, USB Rechargeable Headlight for Aero Road & Commuter Bicycles with Multiple Modes by Ben Barrington

I bought this headlight to improve forward visibility when driving during the day. The color convinced me. This thing is small and unobtrusive, bright enough to be seen in daylight, and the battery lasts for 8+ hours of driving. It's so bright that on a cloudy day or just before sunrise/sunset I can see the light reflecting off all the street signs in front of me. Even in the middle of a clear glass I sometimes see a reflection. This light embodies the saying "size doesn't matter". It also works well as a reversing light for night driving.
