12mm Diffused Thin Digital RGB LED Pixels (Strand of 25) updated 12-22 and you can pretty muchRGB Pixels are digitally controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a 'dot' of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can 'push' them into a 12mm drill hole in any material up to 1. 5mm 0. 06" thick. They're typically used to make outdoor signs. We also have flat backed pixels that are essentially the same, but are not as long and thin.
