4.4. Auto Mode (Max Exclusive)

In Auto Mode, the built-in light and vibration sensors manage the light's operation automatically. The light will:

• Enter sleep mode after 30 seconds of stillness or under strong sunlight.

Four blue LED dots on the power button provide a clear indication of the remaining battery level, visible even in daylight. Each dot represents approximately 25% of the battery capacity:

• 4 dots: 75% - 100% charge
• 3 dots: 50% - 75% charge
• 2 dots: 25% - 50% charge
• 1 dot: 0% - 25% charge (recharge soon)

In auto mode, these indicators remain active, allowing you to monitor battery status without interruption.

• Light not turning on: Ensure the battery is charged. Connect the light to a power source using the USB cable. If the issue persists, try resetting the light by holding the power button for 10 seconds.
• Light not responding to button presses: The battery might be critically low or depleted. Charge the light. If fully charged, attempt a reset as described above.
• Smart Brake Sensing or Auto Mode not working: Ensure the light is securely mounted and not obstructed. Clean any dirt or debris from the sensors. Verify the light is in Auto Mode if you expect automatic operation.
