I have lights pretty much everywhere around me.
On my person, without my bags, I have 2-3. My Tange 219B on my car keys, typically my GoliathVN MK2 warm CRI, and the Olight S1R II Cu that I'm carrying for a year straight.
Today, I have added one of Vinh's new D25Cvn 50.2 w/lee filter, rustic/ full AHC, just because.
In my EDC bag, I have a C8Fvn with LH351Ds also from Vinh, and a Jetbeam PC10 in my "oh poop kit" I keep in my EDC bag (has AA/AAA lithium primaries, rubber bands, $40 ish dollars in various denominations, test strips for diabetes, sugar, and a few other things.... basically whatever little I could possible "run out of" and desperately need more on the average day). Also included, would be my Nickel 219b Worm on my main keys.
I've got a rando Skillhunt light on my desk at work, just to have a light here somewhere in the office. This will soon be replaced by my Acebeam EC65 nichia, for lots of reasons.
My car currently has my Sunwayman D20A w/ primary AAAs and an Armytek Prime A2 Pro w/ primary AAs.
This may all sound nuts, even here, but damn it's been quite a long time since I've last needed a light and didn't have one. I have no particular and spectacular story to go along with, I guess that's one of the results of being prepared!
