Adjusting Brightness Modes

The RHL 3000 offers six distinct lighting modes to suit various riding conditions:

• Low Beam Modes (Single Press): Cycle through 1500 Lumen (A Gear), 800 Lumen (B Gear), 400 Lumen (C Gear), and 200 Lumen (D Gear) by single-pressing the low beam button.
• High Beam Modes (Single Press): Cycle through 800 Lumen (E Gear) and 1500 Lumen (F Gear) by single-pressing the high beam button.
• Combined Beam: When both low beam and high beam are activated simultaneously, the light can reach its maximum output of 3000 lumens.
• Warning File (Flashing): Double-press either button to activate the warning file mode, where the far and near lights flash alternately.

Charging the Headlight

The RHL 3000 is equipped with a USB Type-C charging port for convenient recharging. Connect the provided USB-C cable to the light and a compatible power source (e.g., laptop, wall adapter, power bank). The indicator lights will show the charging status:

• Red Light: Charging in progress.
• Green Light: Fully charged.

A red light at the tail will flash when the battery power falls below 15%, reminding you to charge.

The bike light supports USB Type-C charging, allowing convenient recharging from various sources such as laptops, power banks, or wall adapters. Red lights indicate charging, while green lights indicate a full charge.

Power Bank Functionality

The RHL 3000 can also serve as a portable power bank. Use the output interface at the tail of the light to charge your mobile devices, such as smartphones, when needed.

The bike light features a 10000mAh battery and can function as a portable power bank, allowing you to charge other devices like smartphones via its USB-C output port.

Intelligent Temperature Control and Battery Life

The headlight incorporates intelligent temperature control to ensure durability. If the lamp bead temperature reaches 158°F (70°C), the light will automatically shift to a lower setting to prevent overheating. Additionally, low voltage protection restricts output to 400LM/200LM when power is below 15% to protect the battery.

6. Maintenance

To ensure the longevity and optimal performance of your ROCKBROS RHL 3000 Bike Headlight, follow these maintenance guidelines:

• Cleaning: Wipe the light body and lens with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the surface or lens.
• Water Resistance: The light is IPX6 waterproof, meaning it is protected against powerful water jets. While it can withstand rain and splashes, avoid submerging it in water for extended periods. Ensure the USB-C port cover is securely closed when not charging to maintain water resistance.
• Battery Care: For best battery health, avoid completely draining the battery frequently. Recharge the light regularly, especially if it will be stored for an extended period. Store in a cool, dry place.
• Storage: When not in use, store the headlight in a dry environment away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your ROCKBROS RHL 3000 Bike Headlight, refer to the following common problems and solutions:

• Light does not turn on:
  • Ensure the light is unlocked. If the red light at the tail is flashing, press and hold both buttons simultaneously for 5-10 seconds to unlock.
  • Check the battery level. If the battery is critically low, the light may not turn on or may only operate at a very low setting. Charge the light fully.
  • Ensure the power button is pressed and held for 1.5 seconds to activate.
• Light is not charging:
  • Verify that the USB-C cable is securely connected to both the light and the power source.
  • Try a different USB-C cable or power adapter to rule out faulty accessories.
  • Ensure the power source is active and providing sufficient power.
• Light output is dim or inconsistent:
  • Check the battery level. Low battery can result in reduced brightness or automatic mode adjustments due to low voltage protection.
