I carry Inova X5s, but really I wish they were brighter and worked with std batteries. I know there are tons out there, but I haven't researched them much. While at the Ford house the other day, they had these little LED flashlights that were pretty cool for about $13. They had two different shades of brightness, but I don;t know what kind of batteries they use....we were in a rush. They were about 3-1/2" long and a little larger in diameter than the X5. Looked like maybe 8 or 9 LEDs, but don;t hold me to that.
