My EDC plus one extra. For years the EDC has consisted of a 2xCR123 sized pocket light and a variable keychain light. Currently a Quark 123-2 Tactical R5 and an iTP A3 EOS Upgrade.
The extra is currently either the Streamlight Polystinger LED C4 from my truck or my Olight M20 Warrior Premium R2. The Polystinger is nice because it puts out plenty of light, throws far and is rechargeable. I am about to purchase my first Li-Ion batteries and charger, though, including an 18650 for the M20 so it will probably become the dog walking light.
During the winter the dog doesn't get walked in the dark very much because of the cold, but in the summer that will be the routine as it will avoid the HEAT we get here in the South. Well, it will avoid some of it
