ok, clean with alcohol anyway.
also, use some very very fine sandpaper on the end of the body tube, because as aluminium ages, it develops a non conductive, invisible oxide layer.
we want to make sure your body tube is making good contact.
also, google says
there is a review here
from 10 years ago,
of a 3 mode programmable version of the Akoray K-106, plus another version with 5 non programmable modes, plus the one on Fastech that is a single mode
so, I dont know where to send you to find a new driver… for your old light.
since the light has PWM, in some versions, maybe that is what you are seeing as flickering.
one thing that makes flicker worse, is a low battery. I have a couple of lights that flicker when it is time to recharge the battery.
Does your light flicker when the battery is fresh?
