A low voltage yard decoration system uses a power supply and cable, previously intended only for lighting systems, to improve safety, facilitate installation, and increase utility of various decoration designs. The low voltage decorations are an alternative to decorations requiring direct connection to an AC outlet. Where decorations contain lamps, a switch in each decoration allows on-off control of lamps from within the decoration itself. Decorations may also contain electric motors, and these too may be switched from within the decoration. Decoration units attach to the low voltage cable using connectors containing contacts which pierce the insulation of the cable. No tools are required for installation. Decorations may be added to existing low voltage lighting systems or installed as a standalone system. A timer may be present in each decoration, to initiate switching on or off of lamps or motors within the decoration. Decorations may also be remotely controlled through the transmission of control signals over the low voltage cable. Receipt of control signals initiates switching on or off of lamps or motors within decorations equipped with an appropriate receiver circuit. Decorations may also have an associated identification code. This allows transmitted control signals to be addressed to a specific decoration or group of decorations.
