9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | Device is locked (first-time use). Battery is depleted. |
Simultaneously press and hold both switches for 5 seconds to unlock. Charge the headlight fully. |
| Light automatically switches to a lower mode or turns off. | Internal temperature too high. Battery is low. |
This is a safety feature. Allow the light to cool down. Charge the headlight. |
| Charging indicator light does not turn green after prolonged charging. | Charging cable or adapter issue. Battery over-discharge. |
Try a different Type-C cable and USB adapter. If the battery was completely drained for a long time, it might take longer to initiate charging or require a specific sequence (as mentioned in some user reviews, try discharging slightly via power bank function then recharging). If issues persist, contact support. |
| Headlight feels loose on the handlebar. | Mount not tightened sufficiently. Headlight not fully rotated into mount. |
Re-tighten the handlebar mount with the hex wrench. Ensure the headlight is fully inserted and rotated until it locks. |
