You’re going to need a frameless mirror and the lights. Wipe down the mirror and using a measuring tape mark the center of where you’re placing the light with a sharpie.
Place the lights at equal distance from each other; the ones at the top are going to be a little bit more spread apart than the ones on the side. Start to stick them from one side and move on to the opposite to make sure both sides are symmetrical.
Lastly, stick the lights to the top side.
Tape the wires to the back of the mirror.
