I don't. One is on my nightstand, one is in my handbag, two are in my camping gear, and one is attached to my bicycle. Apart from the two reserved for camping, the others are always in use, and therefore cannot be "protected". The ones for camping are in my camping gear, which could serve as a "go bag", if evacuation is called for. It probably won't be, since where I live in Northern New England, we are well above sea level and inland, my location is not in danger of flooding in any way, and the area is seismically stable and rarely hit by major storms. The worst things that could possibly happen are some sort of nuclear accident at the decommissioned reactor less than 5 miles away (exceedingly unlikely, as the only thing left on site is the spent fuel), or maybe perhaps a train derailment, as the rails are less than a mile away.
If my house burns down, it will be bright enough that I won't be needing a flashlight, assuming I manage to escape the fire, and if I do escape, my handbag is definitely coming with me.
Any other lights I might own aren't important.
