Flashlights:
-Surefire 6PL machined aluminum LED flashlight. It uses a pair of 123a batteries that seem to last long enough for me not to complain about changing them.
-Streamlight Scorpion Xenon bulb. Super bright but it eats 123a batteries. Bulbs can go as well. Mine was inoperable for a while until I cannibalized a donor. I eventually ordered some parts.
-Mini Maglite w/Nite Ize LED & switch upgrade. The Mini Mag was sitting around doing nothing and the extra parts I found at Target. It works better than a regular AA Mini Mag.
