This is a real deep subject, especially if you package it in and around modern flashlights. As is the case in modern police and military training. There is so much information on this and professionals take 2 and 3 full day courses and often walk away happy they did!
Through the years I have been on a 6 hour class and have co-hosted and helped organize and ramrod probably 15 or 20 of these courses. Also, we usually have low-light/no-light gunfights at our 4 day combat camps.
In London once, in a huge, trashed-out, multi-floor, building Hubbard found, looked like a left-over from WWII bombing, we did an entire sims course on shooting in low-light and no light in this place. War gaming it all out. Pretty awesome. Put on your flashlight in that one? You could be dead in a second.
Show of hands...how many times have I just turned off the lights in the middle of any hand, stick, knife and gun practice. I often flick off in parts of the room. All the room. etc. But, if the room has windows and it is daytime, this is useless.
And there are huge lists of tips (and yes...those police and military tips are in Gun 2 chapter in my
Training Mission Two book ...sorry for the plug again...but there is really is quite a number of them.) So Yuriy, you might try-
http://www.hockscqc.com/shop/product4.htmlThe book has the largest list of tips and advice you'll find- I know the hard way because I have had to research everyone else's and collect the tips.
Many other books on this subject are just often disguised catalogs for the latest flashlight companies. Giant print. Thin.
Basic "indexing"
...as mentioned has been called many things through time and one tip is simply using your body parts (usually your hand?) to guess where the the rest of the body is. So, If you grab head hair-the height or your body while standing-guess where his neck circumference is? It is very instinctive once you get the point. If you just hear him close by? Low punches, or stabs to the torso? But you know what the word index means and can figure that out.
But is to be REALLY, dark-dark-dark for that, like a windowless, dark basement, to get caught in these pitch black situations. Or you need to be blinded WITHOUT the distracting pain of having just been blinded, to function.
Tactical training. Practical. Situational. Positional. Figure out what is likely to happen in your life, in your world. Crisis rehearse that! Then work out from there to the least possibilities. Many fundamentals cross-over.
For most people, a scary trip to their basement, their kitchen, or a nighttime, roadside, car break down are good places to start.
