Abstract: This invention provides low voltage lighting assemblies and lighting systems that are easy to install, and are particularly useful in landscape lighting applications. Electrical connections between all components, including lighting assemblies, switches, power supplies, etc., are simplified through use of connectors. In one embodiment a lighting assembly comprises a circuit card having first and second zones, and a spanning zone that separates the first zone from the second zone by a selected distance. The electrical connectors and other elements are disposed in the first zone, and at least one lighting element such as an LED is disposed in the second zone. Installation of the embodiments requires little or no modification of the structures in which they are installed, since the spanning zone is adapted to span across the structure.
