Hi,
my B158 begins to flicker when it gets hot, is there any recommendation what to examine to make the flicker disappear? Maybe some bad soldering, or what cause this?
Besides, is it possible to change the 5 Modes of my model, I only need the Mid and High modes, without the flashing modes at all. Any way to change this? What art do I need to order, is it somehow coded to the power on switch?
Many thanks!
