Changing Lighting Modes
The XOSS XL-1200 features 6 distinct lighting modes:

- Medium Light Mode: Balanced brightness for general riding.
- Low Light Mode: Reduced brightness for extended battery life or less demanding conditions.

To cycle through the modes, short press the power button while the light is on.
Battery Level Alert
The headlight is equipped with red power indicators on the side. These indicators will illuminate when the battery level drops below 20%, reminding you to recharge the device.
Maintenance
- Cleaning: Wipe the headlight and lens with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Water Resistance: The headlight has an IPX6 waterproof rating, meaning it is protected against powerful water jets. It can be used in rainy conditions, but it is not designed for submersion.
- Storage: Store the headlight in a cool, dry place when not in use. For long-term storage, ensure the battery is partially charged (around 50%) to prolong its lifespan. Recharge every 3-6 months if stored for extended periods.
