I figured that with a cool-white LED strip, a little dimmer switch, some wire, some glue, and a source of 12V DC power, I could turn the vertical wall mirror I own into a giant lit makeup mirror. Once the strip segments were glues down, I soldered wires in the corners of the mirror, connecting the strips to each other, and also to the dimmer. These can only be cut every 3 LEDs, and so it wasn't possible to make them go exactly all around the mirror, covering the whole perimeter, I needed to leave gaps, and connect the multiple pieces of strips with wire.
