Is there a current (amps) limitation for the Morse key?
There exists a remote switch option for many lights (including the C8 ) which might be quite straightforward to modify.
i would get something with Anduril UI, because it can also be put in other modes.
But it has a nice ‘morse code mode’, too.
if you put it there, it stays there til you turn it back off.
i would also slightly recommend NOT getting a super narrow beam ‘thrower’.
Since most flashlights can be seen for miles even if the beam is somewhat diffuse, and you may not be able to hit your ‘target’ with a .01 degree beam angle.
