How do I cycle through lighting modes on my Amzyigou 1915B flashlight?

[DiElias]

To easily switch between lighting modes on your Amzyigou 1915B flashlight, follow these simple steps: First, activate the flashlight by pressing the tail switch. After the flashlight is on, lightly press the tail switch halfway down to cycle through the available modes. Each half-press will advance you to the next mode in sequence: High, Medium, Low, Strobe, and SOS. Continue half-pressing the switch until you arrive at your preferred lighting mode. To confirm and lock in your selection, fully release the tail switch. Note that the Amzyigou 1915B defaults to High mode each time you turn it on. To power off the flashlight, either cycle through all modes until it shuts down or press and hold the tail switch for approximately 5 seconds. For more detailed information or troubleshooting, please consult your Amzyigou 1915B flashlight's user manual.
