Review on Enhance Night Cycling Safety with Greerride Rechargeable Bike Helmet Light - Flashing and Steady Modes for Increased Visibility by Leo Black

I expected it to be cheaper. Fortunately, this is not the case at all. The lamp is very well made, albeit a bit heavier. However, the battery life helped me get through a few days of driving. With front and rear lights up to 5 o'clock he didn't die. It is impressive! I'm on the go for an hour and a half in each direction, so battery life is key, as is brightness. The rear red turn signals aren't particularly bright, but they're acceptable. The front light has excellent brightness.
