Get a quality LED flashlight. I like the AA lights from Fenix and 4Sevens. 4Sevens' Quark AA2 is a great light IMO. Its single AA sibling is a bit smaller and gives up little in performance. Fenix also makes a very high quality light -- L2T and LD20 are both two AA battery lights. All lights mentioned use common, easy to obtain batteries. Welcome to the forum.
