Tail Cap Glowing Blue - How to turn off? Tool AA 2.0

The tail cap button in my Lumintop Tool AA 2.0 has a light in it. How do I turn it off? How much electricity will that blue light burn? Drain the battery in days, weeks?

Also, how do you get it to stay at the same intensity? With convoy you just let the light run for 3 seconds and then it knows what you like. With the Tool it seems to be at a different intensity each time.

Just a guess, but probably between 2 to 6 months on. The intensity should be close to the same, it’s set by the current limit resistor’s on the switch pcb.
You can double or quadruple the resistor value by changing it out to give you double or quadruple the on time. By raising the resistor value the leds intensity will lower.
I dont like my lighted tail switch to bright so I usually use something around 100k. Experiment in value to see what you prefer.
If you need to turn it off unscrew the tail or head until it shuts off. A more permentant way would be to remove the resistors, if you dont want the feature at all.

The Tool AA 2.0 I believe has mode memory. Meaning whatever level you turned it off in, it will come back on in. Unless there is some special edition I wasn’t aware of. Just had to check mine, it indeed has mode memory. I think the only Tool that has the lighted tail cap is the new Ti version. Again, I’m not sure about that either. I don’t know if that Ti Tool has a different driver or not. One things for sure, mode memory or not, it shouldn’t come on in a random mode every time. What does your manual say about that?

Enjoy the lighted tail cap if you like it. You can always swap it out with a non lighted tail cap. Or if you are handy, take moderators advice.

Forgot to add. If you don’t want the tail cap lit up while you aren’t using it or carrying it. A slight unscrewing of the tail cap should shut if off while not in use.

I didn’t care for the lighted tailcap either on mine but my daughter wanted it on her Panda tool so we switched. She has the lighted one and I have the the standard black one. You could turn the tailcap or head a little and it will go out or do what I did and just switch it with a standard one. The tailcaps on the titanium and aluminum lights are identical.

Or just use a AA battery, the lighted tailcap only works with a 14500.

As far as the memory is you need to keep the light on for at least two seconds for the memory function to work.

In order to turn it off, you will need to remove the switch and disconnect the resistor(s) or LED (s). Blue LEDs are actually quite efficient, not as efficient as green, but pretty good. The blue tailcap in my JAXMAN E2L draws just 0.21 mA, so it lasts 1.6 years with a Samsung 30Q battery.

Have you tried to measure the current?

What a weird feature. How much it drain the battery?

I just twist the front of mine to turn it off. Doing this also makes sure I don’t accidentally turn it on while it’s in my pocket!

That’s actually the correct way according Lumintop

One thing to take into consideration is if you loose you’re light etc. that blue glow will help you out big time. I lost a tool AA 2.0 in our field but it didn’t have the blue light on it. I sure wish it did. It would have given me a greater chance to track it down. in which is still lost till today.

Does anyone have a link to a tail lighted Tool AA V2?

Im in UK and cannot find one, Amazon US wont ship here due to lockdown restrictions.

I ordered this one and a white one and they both showed up with tail switch lights. I prefer an unlit switch for EDC, but it's not the worst thing in the world.

The Tool Ti also comes standard with a lit switch.

I just put a small screwdriver against the LEDs to push them off.
I liked them, but disliked the 8mA drain.
Drained a cell in a few weeks

My ToolTi tail has 6 leds, is just as bright as stock, and pulls just 0.6 mA :smiley: (ok, it was a lot of work :innocent: )

(BLF-A6 driver, 690 Ohm bleeder, 630nm leds on a ring-PCB with 4 KOhm resistance shared)

Since this light doesn’t have LVP, does the blue tailcap light provide any low voltage warning? Not while the light is on, of course, but if you turn it off and the cell is at 3.2V, maybe the blue is off or very dim?

Lol, i just notice today with NiMH aa!

Seems that there are two groups Tool V2 owners here on BLF:
1/ People who got a Tool with a lighted tailcap and don’t want it.
2/ People who got a Tool with a regular switch and want it lighted.
unles I forget the silent majority, which is:
3/ People who have a Tool V2 and like it as it is.

The solution for the first group is very simple, buy a regular Omten switch on 17mm PCB.
There is a catch, because the standard PCB is a bit too wide to fit.
Reduce the diameter of the PCB to about 16mm and all will be fine.
That takes about 1 minute on a bench grinder, or a lot of elbow grease when using a file.

Personally I think it is a bit of a waste to destroy a standard lighted Lumintop switch.
But then again: who am I to tell you what (not) te do?

You are wrong I got both tailcaps!

I think lighted tail caps are like crenellations and bottle openers, a result of feature creep and a needless feature. Do one thing, do it well, do nothing else, do not try to make it something that it is not. I have a knife and a bottle opener… don’t need a knife and a bottle opener on every other tool. I have an emitter on the front, and light should come out the front, not the back. If I need a way to find a light in the dark that is off, this problem has already been solved far more ideally and elegantly with glowing tape or trits. It isn’t just some flashlights, far too many things have too many lights on them, take anyone’s home, and the kitchen utilities and den cable box and modern receivers are filled with useless lights, ruining the dark of night with blue light. Car dashboards are now filled with useless lights, and they can be blinding. Technology, in a lot of ways, needs to get over how cool LEDs are, and stop sticking them on ever damn thing for no reason.

Seems that blue is the most common color for lighted tail caps, and that is even more unfortunate, as blue is brightest, resets circadian rhythms to the opposite of natural, and will cause insomnia, not kidding. If you’re going to have a light in the tail, it should be red to avoid messing with your sleep. While locking out the light, if the light will lock out (unlike my BLF Cu X5! Love the light, but with that feature the designers here jumped the shark), so locking out is a way to turn it off, but there should be some driver-based control. The way they are implemented, as far as I have seen… it is just not a mature feature, sort of an afterthought and slapped on there.

Anyone knows an AA (not 14500) light that has a lighted switch ?

Henk4U2 — Couldn’t you just remove the led or resistor from the board that’s in the tailcap? You have to get the PCB out of the tailcap, but same if you’re replacing it.

nocturne — while that’s a really long rant about a little blue light… I kinda gotta agree. Glad I have a 2009 car without much on it ( no obnoxious big screen for one thing). There are more than a few things I have with a bit of black tape or sharpie ink over a LED and, yes, usually an OBNOXIOUSLY BRIGHT blue one (looking at you - BT speakers) that is sometimes blinking, to boot. OTOH, the dim blue tailcap isn’t going to mess with anyone’s sleep unless they hold it on their eyeball, in which case they have other issues. I would agree that it is an afterthought, and a bad feature, based only on how quickly it drains batteries. That’s WAY too much standby draw. WAY too much.

Easiest way to turn it off? Use NiMH instead of 14500.
