• Charging Port: The light uses a USB Type-C port for charging. A compatible cable is included.
• Power Source: Connect the light to any standard USB power source, such as a computer, wall adapter, power bank, or car charger.
• Charging Indication: The battery indicator lights will show the charging progress. All four dots will be steadily lit when fully charged.
• Battery Capacity: The 1000 Lumen model features a 2000 mAh lithium battery.

It is recommended to use the provided cable for optimal charging. Avoid prolonged exposure to extreme temperatures during charging.

5. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Suruid Bicycle Headlight.

• Cleaning: Wipe the light body and lens with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the finish or optical components.
• Water Resistance: The light has an IPX-4 waterproof rating, meaning it is resistant to splashing water from any direction. While usable in rainy conditions, avoid prolonged immersion in water.
• Storage: When not in use for extended periods, store the light in a cool, dry place. Ensure the battery is partially charged (around 50%) before long-term storage to preserve battery health.
• Heat Management: The light's aviation aluminum alloy shell aids in heat dissipation. If the light becomes excessively hot during prolonged high-brightness use, it may automatically dim to protect internal components. This is a normal protective function.

6. Troubleshooting

If you encounter issues with your Suruid Bicycle Headlight, refer to the following common solutions:

• Light Not Turning On:
  • Check battery charge level using the indicator lights.
  • Ensure the power button is pressed firmly.
  • If the light has been stored for a long time and won't turn on or charge, try a "trickle charge" for 5-10 minutes using a low-power USB port (e.g., a computer USB port) before attempting a full charge with a higher-power adapter.
• Light Dims Unexpectedly:
  • This is often a thermal protection feature. If the light gets too hot, it will automatically reduce brightness to prevent damage. Allow it to cool down.
  • Check battery level; low battery can also cause reduced brightness.
• Charging Issues:
  • Ensure the USB Type-C cable is securely connected to both the light and the power source.
  • Try a different USB cable or power adapter.
  • Verify the power source is active.
• Mounting Instability:
  • Re-tighten the bracket screws on the handlebar.
  • Ensure the correct gasket size is used for your handlebar to provide a snug fit.
