And if you carry the light only for serious and use something else for in-close etc, there are single output versions of the Fury. Bravo Company carries one version that is theirs alone, spec'ed by Pat Rogers. FWIW, use ONLY Surefire CR123 batteries - best quality, and amazingly cheap when purchased in bulk compared to getting a pair in the store.
There are other advantages to the bright light, too. (BTW, I can pick up the reflectorized street signs at well over 1/4 mile.) I walk my cranky dog in the dark this time of year - the sun does not come up until after I leave for work and is long set by the time I get home. He needs to be kept away from other people, and a bright light lets me pick them up at 100 yards and change my path to avoid them. I am also able to check out anything that gets his attention - small animal, people, whatever.
I pretty much carry at least one light all the time (I have a BIG Olight with a Cree head in my car that I used to carry on patrol along with a G2X on my belt). If I need to assess a threat, more light helps. It is a (very short term) distraction, lets me see more, and along with my cheerful pleasant demeanor,

convinces others that I really mean what I say. A knife, pistol and reload, light, and cell phone with earpiece are stuff I try to have with me at all times.
