I EDC an ASP saphire light on my keychain. I don't consider this carrying a light just carrying my key chain. I also make sure to carry my AA maglight and my photon II both of those are part of my kit. I don't even think about the ASP on my keychain - until I need some light then it is the one I use since it is more conviently available there hanging from my keys looped onto my belt. the ASP isn't the best light I carry but it is the most used. It is also still running after all these years.
