## Abstract

The invention relates to a glazing having a first anchoring support being configured to engage with an electrical connector that is part of an electrically actuated device comprising at least one electrically actuated component and first and second electrical connectors that are connectable with an electrical power supply. Upon electrically connecting the first and second electrical connectors to the power supply, the electrically actuated component has electrical power supplied thereto and is in an energized state. When the first electrical connector is engaged with the first anchoring support, the electrical device is releasably fixed to the glazing. Connecting the power supply to the first anchoring support and the second electrical connector causes the electrically actuated component to switch from an unenergized state to the energized state. Mounting arrangements and vehicle lights to be mounted to a component of the structure of a vehicle are also described.
