Review on 🚴 High-performance Topside Bike Helmet Light - 43 Hour Dual Front & Rear Bright Light. 100 Lumen, Waterproof & USB Rechargeable Bike Light. Perfect for Enhanced Visibility and Safety of All Cyclists. by Jeff Sprunk

This is a must-have item for those who ride their bikes around the big city. It's ridiculously bright with no glare, ideal for daytime use. The beam is wide and unfocused, so you can't use it as a headlight, but that means other people on the road don't have to be directly in the beam path to see you clearly (even during the day). Battery life is also pretty good if you use it in flash mode. The button is also large and clickable, making it easy to find it on your head even with gloves on (if you have it installed on your helmet).
