5. Maintenance
5.1 Cleaning
Wipe the lights with a soft, damp cloth to remove dirt and debris. Avoid using abrasive cleaners or solvents that could damage the casing or lens.
5.2 Storage
Store the lights in a cool, dry place when not in use. For long-term storage, ensure the battery is partially charged (around 50-70%) to prolong its lifespan. Recharge every 3-6 months if stored for extended periods.
5.3 Water Resistance
The DARKBEAM DB06 is IPX5 waterproof, meaning it is protected against low-pressure water jets from any direction. It is suitable for use in rainy conditions but should not be submerged in water.

To maximize battery life, avoid fully discharging the battery frequently. Charge the lights regularly, especially after heavy use.
6. Troubleshooting
- Light not turning on: Ensure the battery is charged. Press and hold the power button for 2 seconds to activate.
- Light not charging: Verify the USB-C cable is properly connected to both the light and the power source. Try a different USB-C cable or power adapter.
- Dim light output: The battery may be low. Recharge the light. Ensure the lens is clean.
- Headlight feels bouncy on handlebar: Ensure the mounting bracket is securely tightened. The rubber strap should be firm. Re-adjust the position if necessary.
- Cannot turn off without cycling through all modes: For the headlight, a long press (2 seconds) should turn it off directly. If it cycles, ensure you are holding the button long enough.
