How can I install a vanity light in my bathroom?

To install a vanity light in your bathroom, first turn off the power to the existing light fixture. Remove the old fixture and disconnect the wires. Install a mounting bracket for the new light fixture. Connect the wires from the new fixture to the existing wires, following the manufacturer's instructions. Attach the new fixture to the mounting bracket and secure it in place. Turn the power back on and test the light to ensure it is working properly.
