i just found out that there's a hidden mode on some flashlight with magnetic control ring.
-RRT-3. rotate the ring half way to the 180 lumens and quickly back to 5 lumens. it will actually enter the hidden mode. this mode will slowly turn the light on and off. can i all this mode a standby mode or warning mode?
-Sunwayman V60C. go to the strobe mode and then quickly turn the ring to high and back to strobe( you gotta to do it fast). it will switch to a hidden SOS mode.
