The double-ended flashlight having two conductive barrels and a double ended tailcap insert which provides for enhanced mechanical and electrical contact between the barrel and the batteries, provides for retaining two tailcap springs, one on each end, to the tailcap upon removal of the tailcap from one or both barrels, provides retainers to prevent the tailcap insert contacts from over radial extension and to prevent ingress of material from ambient to within the battery housing.
