Drill pilot holes to prevent splitting the wood, then screw the mounting bracket firmly in place with appropriate hardware. Double-check that the bracket is level using a spirit level before proceeding.

Step 6: Run the Electrical Wire

If installing new wiring, carefully route 14/2 or 12/2 electrical wire from your power source to the mirror location. Hide the wire behind walls whenever possible for a clean appearance and enhanced safety. Secure wiring to studs every 16 inches using staples, ensuring you don’t damage the wire’s insulation. Never leave bare wire exposed in wall cavities.

Step 7: Connect the Mirror to the Power Source

Strip approximately three-quarters of an inch of insulation from wire ends using wire strippers. Connect the hot (typically black) wire to the hot terminal, the neutral (white) wire to the neutral terminal, and the ground (bare copper or green) wire to the ground terminal. Secure connections using wire nuts, twisting clockwise until tight, then wrap the connection with electrical tape for added safety.

Step 8: Mount the Mirror

Carefully position the lighted mirror onto the mounting bracket, aligning all connection points. Most modern mirrors feature quick-connect plugs that snap together for simple installation. Ensure all connections are fully seated before securing the mirror to the bracket using provided fasteners.

Step 9: Install the Switch or Dimmer

Mount your switch or dimmer in an easily accessible location near the mirror or bathroom door. Follow the manufacturer’s instructions for proper wire connections, typically connecting one hot wire to the switch and routing it back to the mirror. Use a voltage tester to ensure no live wires are present before making final connections.

Step 10: Test Your Installation

After all connections are complete, turn the circuit breaker back on and test your lighted mirror. Check that all lights illuminate properly and that any switches or dimmer functions work as expected. Verify that the mirror sits securely on its mounting bracket and that all electrical connections feel secure.
