A lighted artificial tree includes a first tree portion including a first trunk portion, first branches joined to the first trunk portion, and a first light string. The first trunk portion has a trunk connector and a first trunk wiring assembly, the first trunk wiring assembly is electrically connectable to the first light string and the trunk connector, and at least a portion of the first wiring assembly is located inside the first portion. The second tree portion includes a second trunk portion, second branches, and a second light string. The second trunk portion has a trunk connector and a second trunk wiring assembly, the second trunk wiring assembly electrically connectable to the second lighting string and the trunk connector. The second tree portion may be mechanically coupled and electrically connected to the first tree portion by coaxially coupling the first trunk portion to the second trunk portion.

Various components for artificial candles and other lighting devices are described that can be used to create a realistic flame effect in the devices. The devices include a flame element that extends upwardly from a housing. A light source can be disposed with respect to the flame element such that the flame element is illuminated. A variety of drive mechanisms could be disposed within the body of the device that can cause movement of the flame element with respect to the housing. The flame element can be coupled to a housing or mounting bracket of the device using various components to suspend the flame element within the housing.
