This video is clear and useful -- thanks for posting your LED troubleshooting guide.
Thanks so much for this video. I have a nice, bright Husky LED flashlight that stopped working. I was able to determine the tail cap switch was a little loose and tightening with the use of needle nose pliers as you suggested did the trick!! I would have never figured this out. I'll have plenty of light when taking our dog out late at night.
Cleaning the contacts like you said work I have an xr9 stowed away brand new in box case today I took it out but did not turn on its a new battery pack. I was dumbfounded I followed your instructions on cleaning the contacts with alcohol and sure enough it worked thank you for that simple tip will keep that in mind I understand from olite These batteries are on backorder
Hello I love your video.
I have a 3 Watt 2D digital Brinkmann flashlight which has a display and buttons for off/on, Test and battery status divided in 3 sections.
Yesterday it was working but i press the test button and now doesn't work.
I am afraid that the problem is in the microprocessor, because I bought it used, I wonder if letting it without batteries for some days, the capacitors will drain and the problem will be solved.
Would you have any suggestions for me please?
How to correct led module circuit if that is not working?
My flash light is the Led Lenser P5R2. I have had for 2 years now and I like it but the switch seems to be have a problem can you assist me on how to repair the switch with the video here on You Tube. When Im charging it the light for charging does not show and this occurred after it had fallen about 1m onboard the ship.
What if you have a Duracell led flashlight? Looks like the taillight switch is snapped into place, not screwed in.

How to install batterys

Since the fit between the flashlight body and batteries is so tight, any battery deterioration can make the batteries unmovable and they are stuck. The Front end of LED flashlights are not easy to remove, depending on the model. Is there anything we coat the battery part of the flashlight with to make it easier to remove batteries if they deteriorate? I have had to discard two $40 flashlights when the AA batteries corroded a little and they became stuck in the flash light body.

Hello, the problem of not charging the flashlight battery happened to me. I tried with different batteries, but it does not charge again. Please help me.
Bro my led flashlight drain battery fastly.. With no reason..
After charging the battery it will be okay but within one week without even using the flashlight battery drains
Where do you look if light cuts out after 10-20 secs? Charged fresh batteries were used...it just shuts off and then I restart ot and same thing. 10-20 secs
I have the same problem but haven fix it .
Mine does the same thing
Torch work only when it connect with electricity
I find that 95% of the time the problem with flashlights that use three AAA batteries in a little plastic holder, is that there are 4 to 6 places where a coil spring has to make contact with a thin metal contact. One or more of the spring surfaces or contact surfaces gets corroded. They may still look shiny and new, but you may have to scour ALL of those surfaces (including the springs) with a piece of sand paper.

problem nitecore chg finished
is that a badger on your face?
🤣
No it is not... it's a giant rat buddy
Is that a dick on your head? Yes it is, a little micro dick if that
decent vid; but usa, business 'for the sake of it'..
Do t know why everyone posts the same old shit, my granddaughter can jump out a tail cap, mine still won’t come on, it’s in the head assy, why. Any anyone make a trouble shooting video on find the problem & fixing it. Everyone can solder in a led, how to find the problem in The head. Obviously it is harder than hell to disassemble and troubleshooting it finding the problems
Boy that was useless....
Ooohh ur cute
