DIY LED Strip Backlit Mirror

Many DIY mirror projects use a low-voltage 12V or 24V LED strip with a matching power supply. The strip voltage, power-supply rating, and connector polarity must match before the circuit is energized.

The strip is usually placed around the rear perimeter of the mirror using its adhesive backing or an aluminum channel. Cleaning the mounting surface and adding mechanical support helps prevent the strip from peeling away over time.

Yes, but bathroom installations need careful separation between low-voltage lighting, the mains power supply, and areas exposed to water or condensation. A qualified electrician should handle the mains connection and confirm the installation meets local electrical rules.

A backlit mirror places the LED strip behind the glass, producing a halo effect around the edge rather than lighting the face directly. A front-lit vanity design generally gives stronger task lighting for makeup or shaving.
