These strip lights have LEDs that can turn 16 different colours & change between flashing, strobe, fade, & smooth modes. Control them from the included remote control. They’re easy to apply. Just cut the length you need, peel off the backing, & stick them! Please note, once you cut the strip you can’t use the excess. Stick them behind your PC monitor or TV, under the edge of your desk, or even under your kitchen counters for awesome ambiance!
