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

[OCamille]

Changing the lighting modes on your Amzyigou 1915B flashlight is simple. Here's how: First, turn the flashlight on using the tail switch. To cycle through the modes, gently half-press the tail switch. Each half-press will advance you to the next mode: High, Medium, Low, Strobe, and SOS. Continue half-pressing until you reach your desired mode. To keep that mode, simply release the tail switch. Note that the Amzyigou 1915B always starts in High mode when powered on. To turn the flashlight off, either cycle through all the modes or press and hold the switch for about five seconds. For detailed information and troubleshooting, consult the Amzyigou 1915B user manual.
