i third the flashlight
i have a multi-mode flashlight on top of my safe
(i bought it from a forum member who assembled it from parts, but you can get them on ebay or amazon)
it has a "moonlight" mode that allows you to open the lock without ruining your night vision too much or give away your position to an intruder
by clicking on the end cap, you can make it a regular flashlight or an extremely bright one
and the battery is rechargeable
...
my post is going to get slightly off track.
It is good that mac also advocates a flashlight. But it seems like a very fancy light. Maybe too fancy?
Being of an older age group, I advocate something a little simpler. And/or a second flashlight at the safe location.
Especially if you intend to get into the safe for your primary hd firearm. Kind of like a cop who carrys a backup pistol in an ankle rig.
Personally, i don't keep my primary in a safe. There are enough quick access pistol solutions available.
And while we're on this topic, I also keep tactical style flashlights all over my house.
Not necessarily because I'm a paranoid gun totin' freak.
It's because after a certain age, your night vision goes downhill....no laugh, you'll all get there one day.
