For work I use a mini mag light, I keep one in each car I drive, and have lost and then found so many that I now have them all over the place. They last forever. I also bought a 5 pack of LED flash lights from Home Depot fro $10, I just put them everywhere. No matter where I look, kitchen drawer, sock drawer, car cup holders, on my desk I see one sitting there.

To save my life at home, I trust this guy

100 lumen LED, green laser, strobe settings, picatinny rail mounting, not cheap, but awesome.
