Books or video / DVD's

[K.H.]

Can anyone out there recomend any books or video's / DVD's on how to build and or modify/upgrade handheld flashlights? Would like to learn how to do stuff like that. I have a few older maglights and other things I would like to upgrade

Thanks

If you don't mind reading, you've come to the right place. Whatever you may want to do has probably been done, or at least attempted and well documented on here.
