Thanks for the heads up Steve!
I will be heading to CostCo for these lights! I like to stick a light in the recess of all 4 doors of our vehicles, drawers in camper, drawers in kitchen in house, etc.. I don't want to go searching for a light when I need one in a hurry. At this price, they are almost "throw away" lights and no big loss if you lose it. Not like a Surefire!
I'm never without 2 (absolute minimum) or 3 lights! When I go through airport security, I'm more often then not asked why I have 3 flashlights in my daypack. My reply, "I'm afraid of the dark!" In reality, I subscribe to the theory, 3 is 2, 2 is 1 and 1 is NONE!
AAA have the best longevity for an emergency light, much better than AA or CR123 lights. And a AAA light will provide ample light.
My favorite 2x AAA cell EDC light is the Pelican 1920 (Gen2). I also have a couple of the 1x AAA 1910s stashed around various places as well.
Pelican 1920 (Gen1) is currently available at Sierra Trading Post for 19.99 and in 3 colors! That's a great deal as well!
And, I always carry extra power source (more batteries)
in this case. The case holds AA, AAA or CR123 batteries.
