5. Operation

5.1 Power On/Off

Press the power button located on the light body to turn the light on or off.

5.2 Light Modes

The VASTFIRE Bicycle Light features 4 distinct lighting modes. Cycle through these modes by pressing the light mode button (often integrated with the power button or a separate button near the digital display):

Floodlight (8 lamps on): Provides a wide, diffused beam for general visibility.
Spotlight (9 lamps on): Offers a more focused beam for distant illumination.
All Lamps On (17 lamps on): Combines floodlight and spotlight for maximum brightness.
Flashing (17 lamps flashing): High-visibility flashing mode for increased presence.

5.3 Digital Display Function

The integrated digital display shows the current battery level and estimated remaining usage time. The charging state increases gradually, while the discharging state decreases gradually, providing real-time information on your light's power status.

5.4 Charging

The bicycle light is equipped with a Type-C charging port. Connect the provided Type-C charging cable to the light and a suitable USB power source (e.g., wall adapter, computer USB port, power bank). The charging port is highly sealed by a rubber ring to maintain its waterproof rating.

Note: The Type-C charging port may also be capable of 'backwashing' (reverse charging) to power other devices, acting as a power bank. Refer to the product specifications for your specific model.

6. Maintenance

Cleaning: Wipe the light body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the charging port cover is securely closed after charging to maintain waterproof integrity.
Storage: Store the bicycle light in a cool, dry place when not in use. If storing for an extended period, charge the battery to approximately 50-70% and recharge every 3-6 months to prolong battery life.
Waterproof & Dustproof: The light features an IP65 waterproof and dustproof rating, thanks to its one-piece die-casting process, high-strength aluminum alloy, and reinforced acrylic inside. However, avoid prolonged submersion in water.

7. Precautions

Water Ingress: Avoid water ingress into the charging port. Ensure no standing water accumulates at the charging port, especially when the cover is open.
Children: This product must be used under adult supervision, especially when children are present.
Direct Eye Exposure: Do not look directly into the light beam, as it is very bright and can cause temporary vision impairment.
Heat: The light may become warm during extended use. This is normal.

8. Troubleshooting

Table 8.1: Common Issues and Solutions
Problem	Possible Cause	Solution
Light does not illuminate	Battery depleted or incorrectly installed.	Charge the battery. If applicable, check battery orientation (positive/negative polarity).
Dim illumination	Low battery, incorrect light angle.	Recharge the battery. Adjust the light angle for optimal visibility.
Light flickers or turns off unexpectedly	Loose connection, low battery, or internal issue.	Ensure the light is securely mounted. Recharge the battery. If the problem persists, contact customer service.
Digital display not working	Light is off, or internal display issue.	Turn the light on. If the display remains off, contact customer service.

9. User Tips

The digital display showing remaining power and estimated time is highly valued by users for its precision and usefulness.
The wide beam of the VASTFIRE light is particularly effective for mountain biking (MTB) at night, providing excellent visibility across the trail.
The robust construction, featuring an aluminum alloy shell, contributes to the light's durability and resistance to impacts.
The mounting bracket is designed to be compatible with various handlebar diameters, including 31.8mm and 35mm, ensuring a secure fit for most bicycles.
Some models with Type-C charging may also function as a power bank, allowing you to charge other small electronic devices on the go.
