Key Features Explained
Mode memory can save cycling through all six options each time the light is turned on. USB charging means the light can be recharged from a USB port, but the charging time and whether a cable is included are unspecified.
Compatibility, Size and Fit
Possible mounting locations named for this light include a bike frame, fork, seat post, handlebars, or helmet. No ring diameter ranges or attachment limits are provided, so do not assume every bike or helmet will fit. Compare the mount pieces with the intended location and check that the light can be secured and positioned without interfering with controls or moving parts.
What to Compare Before Buying
- Confirm that the mount rings suit the intended attachment point; their dimensions are unspecified.
- Check whether a USB charging cable is included and whether your charging setup is suitable.
- Consider the unspecified battery capacity and normal operating time when planning charging between rides.
Before You Decide
Confirm the mount fit, charging arrangements, and battery information for the exact light. The low-battery mode is not a substitute for checking the charge before a ride.
