I mainly used this with a Garmin as a daytime flashlight. It attaches directly to the Garmin bracket, allowing you to mount the Garmin on top of the light, which keeps the handlebars tidy. In the last use, it was possible to use it for about 4 hours with a full charge and flash mode. A USB-C cable is also included. 【High Visibility】 The RAVEMEN FR160 boasts a brightness of 160 lumens and features a warning flash function that is easily visible even during the day.
