B&C MD04 is a wall-mounted mirror that is easy to install. It can be installed in two ways, depending on your needs. The first way is to mark the drilling locations, make holes, fill them with supplied plugs, and install the mounting bracket. The second way is to connect electrical wiring by connecting the live wire to the live terminal, the neutral wire to the neutral terminal, and the ground wire to the ground terminal. Please note that the colors of the wires may differ between households, so if you are unsure, please consult a licensed professional electrician.
