The Sylvwin Vanity Mirror Light Kit is a USB powered light kit that includes 10 LED lights with adhesive stickers for each light. The LED lights have three light colors: warm white, neutral white and daylight white and 10 brightness settings that are dimmable, both controlled via the in cable controller. We have actually not installed these on a mirror yet, but we did test them out and the lights work as intended. We are still in the process of a room renovation and we have only dry fitted the lights to her mirror in case we go with a different mirror, but we are happy with how minimized the cord between the lights appears. Drilled glass vanity mirrors are expensive and the Sylvwin Vanity Mirror Lights is a cheaper alternative that still produces desired lighting at the vanity.
