I made a new tailcap for my D4v2.
It’s only 60,6 mm now!
90 mm in 18650 format.
I also made brass inner threads for my D4V2Ti. It runs super smooth now!!
Family is complete now:
Nice work 
Really cool.
The style may not be my favourite but I really thought that D4 tail was not as compact as I wish it would be - and you made this aspect perfect.
The brass threads are also super-cool. I wonder if some production lights could steal the trick, making their Ti lights even better. 
Thanks!
I love how compact it is right now.
Even with the 18650 it’s Nice and compact!
I allready suggested it to Hank but don’t know if the future lights will include this feature…
What mod could I do to get past this issue? Or, what are my options to find a replacement switch?
Thank you!!
How did you get this nice result Mascaratum? Paint, glow tape?
Yup, I put a small strip of glow-in-the-dark tape around the leds/optic!
Works pretty well after being “charged” through the light ON.
Obrigado Mascaratum!
On your pictures I only see GITD strips around the head, opposite the side switch. I doubt these can be charged by the light itself, correct?
Do you mean you also put some GITD in the front of the light, inside the bezel? If yes, pictures would be welcome.
I would like to make the switch of my D4v2 visible in the dark, but I am far from having the necessary skills to make it lighted. Not sure GITD paint on the rubber switch cover would work, maybe a thin GITD paint strip on the retaining ring, or on the light body around the switch?
I'm glad this conversation got a bump. Hank never responded so I'm thinking about selling that one. However, aren't there some posts on fabricating a switch? I just need that 'blister' like part.
Thank you!
You’re right! :person_facepalming:
I didn’t check my previous post, and I was forgetting that I put some thinner strips on the grooves of the head !
It was also the same thing, cutting them thin enough and making them fit there the best way possible.
I also put a strip inside though! I’d love to show it to you but I don’t have it with me, and it is also damaged, the switch went “puft” so the D4 is in the “boxes”.
Hum, doesn’t the D4v2 have the aux leds? Or did you turn them OFF?
I am not sure if GITD paint would work well. I used it in other things and it is not the best thing… GITD tape is probably a better and more visible option. 
Same thing that happened to me. From night to day it got “stuck” , I took the cover and the small membrane fell off.
I sent PM to Hank and he told me that in my next order he would send a switch. I just didn’t place an order yet :person_facepalming:
Yes it does, and I like them. But after a couple of nights I realize that I’d rather have a luminous (like on the new Sofirn SC31 Pro) or GITD rubber boot on the switch. The aux LEDs are great in locating the flashlight in the dark, but since my goal is to switch it on I’d rather find its switch than its head.

Where did you get yours? glowtec.co.uk seems to have very high quality tape, but they charge £25 to ship a tiny sheet (which fits in an envelope and weighs less than 50g) to ship it from the UK to France
Hi all,
Is there any (not too difficult) mod to improve the anti-roll design of the light (I have D4v2)? I find the grip ridges on the tailcap not efficient enough in this regard. I would like to lay my flashlight horizontally on my bedside table so that I don't risk to knock it over, and with the switch upwards, to find it easily. But because the head does not have rotational symmetry (heavier on the switch side), it needs to be put down very precisely, and is not very stable in this position (rolls too easily).
An hexagonal or octogonal tailcap would do, but I am not able to design and make this. Maybe a sort of tactical ring made of rubber which could be slid onto the clip groove?
Pocket clip?
I've considered the pocket clip option, but it would need to be very wide, and not sure the light will stay in the same position when I press the switch.
This is where I got mine! It is about 10x less than the value you mentioned!!
And believe me, after 8 hours I can still locate a light in the dark.
Not as a tritium vial, but works!
