I carry a 1aaa Copper Maratac all the time. IF I have on long pants (I don't wear shorts) It is in my pocket. Clipped to my Fatboy I have a Fenix E12. In my Malaga (It is in which ever vehicle we are driving that day) I also have a cool CR123 Light Gary gave me AND another 2 cell CR123 light that is insanely bright. Plus I have a larger 2 D cell LED light in each vehicle. Oh and I also have a 2aa LED "Area" light in each vehicle as well.
But as I said above, my edc lights are the Maratac and the Fenix. Both good lights and they have never let me down.
