Maglite makes that same model in LED now, it's super bright and the battery lasts forever. They also have some real high intensity lights that are smaller than that, but cost a bit more. They work well for spotting things in the ocean at night if you're on the cliffs, you see some big fish at night (assuming calm water). I definitely cosign the flashlight suggestion, power goes out somewhat frequently.

A small blade, and decent first aid kit can go a long way as well.
