That is something that just baffles me. Same flashlights but the ones now only come apart into 2 parts?
It will just make it harder to get the flashlight guts out. You won`t need them so don`t worry on busting them but the flashlight head will not be an option.
The flashlight switch could be used but mine is a main shut off and honestly the switch is cheap and there has been times I had to hit it a couple times to turn it on. It could be used but it clicks on and stays on. Rocketman has a thread on making it stop from locking on I believe.
The bottle cap can be pushed in place though through the lens area of the flashlight and then put into place as shown in the photo`s.
So just getting the flashlight part out will be tricky. A socket and hammer will be usefull perhaps.
You might go to the hardware store and check the finishing nuts/washers for the end cap or I like the JB weld myself.
You need a connector of what you prefer and a LED is an option I`d be happy to draw up how to hook that up for you.
Connectors
and JB weld hardens like Metal hope they have that there in Tokyo
From here I`d like to just use PM so not to upset the madvapes forum if it does.
