I think it's important to reflect on Murphy's law here. If your flashlight can fall out of your hand and smash into a bazillion pieces when it hits the floor, then it probably will. Apply it to whatever little delicate anatomical part of said flashlight. Those things, for the most part, aren't meant to be tough. Maglites (those big metal monsters) are the exception. Those things are pretty tough. That may be, but they aren't all too bright. You could have your maglite trained on something close by and only see everything around what you are focusing on due to the accursed halo effect. That's unacceptable I believe.
Focus is a very important factor when it comes down to emergencies/life or death situations. You need to focus on the flat tire, on the person's eyes, on that animal moving through the bushes towards you, and so forth. Flashlights are good for self defense, I would even venture better than carrying a knife or gun. (how are you going to shoot someone when you can't even see them?) now D cell maglites are pretty big lights if you have held one/own one. They are good for self defense in that respect. They are like heavy metal batons. You don't want someone close enough to have to beat them with it though.
I guess some of you may be wondering why I am lecturing you all on flashlight what not and so forth in the first place. I believe it is important stuff to know and a little bit of knowledge I'd like to pass down to you all. Awhile back I went about trying to solve these little flashlight predicaments on my own. I was very pleased with the results. If any of you have been camping with me or have just been around when I decided to show off my flashlight you know I was quite pleased with it. Due to unforeseen circumstances that particular flashlight has left my hands, so I am currently looking for a replacement. This is what I have in mind:
