I have one of those Eveready lights in my truck - always works .

I just ordered 3 Minimag 2AA lights - with the "old fashioned" Xenon bulb ( I have many extra bulbs) - I lose these things, or they get corroded from leaking batteries and I have to throw them out.  The ultimate application of the KISS principal - I looked in 3 or 4 stores for them and nobody carries the minimag anymore, they want to sell fancier, more expensive lights - which I don't want - I have several headlamps that I have to click thru several options every time - hate that.  Nope, KISS for me.
