I personally have an olive drab 'Rip Away EMT Pouch' from Condor. I work seasonally for the US Forest Service and we are encouraged to keep a small first aid kit with us, I wanted something small that I could stick on the side of my line gear, here is a side profile of the pouch as well.
On the inside I keep some very basic stuff, gloves, a few 4x4s/3x3s/2x2s, a few small bandage rolls and bandaids, a small roll of kling and tape, a thing of quikclot, an icepack, an elastic swat-t tourniquet, cpr faceshield, alcohol preps, an antibiotic ointment, hydrocortisone cream, some blister pads and moleskin and a small bottle of eye wash. I also have this pill organizer stuck in there where I keep some basic OTC meds like ibuprofen, tylenol, asprin, immodium, benadryl, acid reducers, and motion sickness pills. I also have a rolled up sam splint I pack that won't fit in my pouch.
It feels excessive to me sometimes for a 'first aid' kit, but when we are way out in the backcountry away from help I am glad I have it. And I like having a little extra (especially the OTC meds) because there is always someone on the crew who didn't pack anything, and I like to help em out until we get back to camp. I also keep it with me during the off season if I go hiking or camping with friends.
As far as flashlights go, I think I saw it here on r/ems but someone recommended the Cree 7W 300LM Mini LED and holy hell are they awesome, plus at $2.31 a piece they are a steal. Solid body, sturdy metal clip, and runs on a single AA battery. I have like 15 of these things, I keep them in all my vehicles, backpacks, tool drawers, etc. I keep one in my pants when I am at work as well.
