Maglites are great, well-built and tough--but not the best product for use around vehicles. If you want excitement, just let a Maglite drop/roll across the battery terminals of your vehicle, quad, etc.
A better choice is a plastic (ie, non-conductible) bodied flashlight.
IMHO, a LED headlamp is the best choice--lightweight, always aimed where you're looking, and is "hands free".

 

the Maglites are cool. Also i was thinking of those ones that you can shake or something and get battery time? has anyone ever relied on these? I never have only because i havent got around to buying one yet, but i was wondering that they may be good, because you don't gots to worry about a battery dying.

 

On the kind of terrain we go on you wouldn't have to shake it much. The terrain will do it for you.

 

Mag light family here. We have them in every size all over the place. Not one has failed me. I beat up one of our big ones and one of the small ones (not the mini, that's for the tackle box) really badly and use them a lot. They keep on working. Replacement bulbs are easy to get and cheap too. Make sure you check it if it's going in a tool box every now and then for battery life.

 

Mag Lite all the way. I still have a 5 "C" cell light from the cop days that I bought back in 1981. You can get the two "AA" lites for dirt cheap and they are just and rugged as the big ones.

 

LED - absolute must.

Battery - standard AA, AAA. Stay away from the $7-$10 3-volt 123 batteries so common in things like Streamlights. When thise 123 batteries go dead, they go dead like immediately. So many times people who don't know this think their bulb went because you go from a light that is nearly 100% brightness to nothing. LOL

Style - If you are going to have just one light it has to be a headlamp! Can't use both hands if you are trying to hold a flashlight. A headlamp pretty much shines where you are looking.

Durablility - I won't hesitate to recommend the Energizer headlamps you see in nearly every store. Most common is the 3 LED which is great. L-M-H, red night light and blinking all in one light. That light is bright but for alot more light look for their 1-watt or micro LEDs.

They are water-resistent, not waterproof. Keep it stored in a ziplock wrapped in an old washcloth in your trunk or whatever. I wrap all my more sensitive things in something in my cargo trunk.

Basic 3 LED Energizer headlamps are like $10.
