As the title says, if you have to pick one light only what would you look for? Do you already have one that fits? I will exclude a good tactical light as I believe one should keep a dedicated gun light with their arm of choice.
For context let's say you are going on extended travels, or downsizing to a small residence or bugging out. Whatever. For me, I'm not really sure. Headlamps are great for practicality but I have used the aaa light on my keychain more than anything else. Of course this form trades a lot of utility for handiness, although with modern LEDs that balance has shifted quite a bit. At this time my handgun light is a surefire g2L with Malkoff m61n.
That said, a 1xAAA twisty keychain light with something like a neutral xpg or even a nichia 219c would be pretty good. I like LMH or MLH order of modes, a strong and reversible clip to use with a ball cap, and of course a higher IPx rating.
