Simple and bright. Has 3 flashing modes and mounts on the helmet with one screw. It does stick out a bit but is not huge. Does the work!

Bright Light That Mounts On Helmet
The light is easy to install on the back of the helmet. It's really bright and has a long battery life. I usually charge it every 5 hours of riding using the flickering mode. Though, I'm sure I'd go a lot longer. I definitely would buy another one
