What does IPX6 certification mean?
IPX6 certification means the light is protected against powerful water jets, making it suitable for use in heavy rain.

Troubleshooting
Light does not turn on
Ensure the battery is charged. Connect the light to a power source using a USB-C cable and check for charging indicator. If charged, press and hold the central button for a few seconds to power on.
Light is not charging
Verify the USB-C cable is properly connected to both the light and the power source. Try a different USB-C cable and power adapter, as the cable might be faulty or incompatible.
Light flickers or turns off unexpectedly
The battery may be low. Recharge the light fully. If the issue persists with a full charge, there might be a loose internal connection, contact customer support.
Mounting is not secure
Ensure you are using the correct size O-ring for the tube diameter. The O-ring should be taut. For added security on rough terrain, consider using additional zip ties or a different mounting solution if available.
