I carry my primary EDC flashlight on a belt loop holster. I find a 2xCR123A light too large to carry in or on a pocket, especially when other items are also carried in the same pocket.
My backup 1xAAA EDC is on a little pouch on another belt loop holster.
My back-backup 2xCR2016 EDC is clipped to my keychain with an easy release hook.
I toyed with the idea of carrying a light around my neck, but I don't like the lack of accessibility when carried inside a shirt or the swinging weight when carried outside shirt.
I once clipped a light directly to my belt, but lost it when using a backpack leaf blower. All my belt holsters are loop holsters now.
If I decided to go with a 1xAA EDC, I might use a pocket clip. However, I already carry so much in my pockets.
The only time I carry a satchel is when I am hiking with my water canteen. No flashlight is included in the satchel. My school backpack used to have a 9 LED light in it, back when I used it daily.
I wouldn't consider a glovebox light EDC.
