A monitor arm with decorative lighting (or luminous display arm) includes a light-emitting element and a wire that is connected to the light-emitting element. The light-emitting element and the wire are routed through an inside cavity of the arm. A conductive slip ring is disposed inside a connecting joint of the arm to facilitate electrical connection of the wire. The monitor arm with decorative lighting includes wiring arranged inside a cavity of the arm so as to not be visible from the exterior providing additional safety and organization for wires and a clean outward appearance.
