LED strip lights can add a ton of personality to seemingly boring spaces, and you can install a smart one for just $17 today.

In addition to a variety of colors and brightness levels, these Minger strips include app (and even Alexa!) control and a built-in microphone that allows the lights to pulse and change according to ambient noise, which makes for a pretty great party trick. I actually installed a similar strip—without the app support—above my kitchen cabinets (pictured here), and usually just leave it set to one color, but the effect is fantastic.
