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

I use this headlight on my road bike as a daytime flash for better visibility. It is excellent for this purpose. Size and installation: very small. I like that it's down and away from the front of the handlebars. The small size makes it very easy to mount on poles. The rubber band is secure and the lights do not vibrate, make noise or move while driving. Battery Life: On average I ride 2-3 hours and the charge lasts the whole ride. Output: At 150 lumens I wouldn't use this for MTB or on unlit roads. As daylight - excellent. Settings: Various settings are good. I like variety. Charging: It doesn't take long to charge and I like that it charges via USB. I don't like that the main light flashes as a charging indicator. It's annoying and distracting when plugged into a computer or sitting on your desk. Overall I like this light, even with the annoying blinking of the charge indicator. For the price and size, it was better than any other USB charging option.
