These auxiliary accent lighting pods may be hit or shaken into mud or damp without worrying about malfunction. Whether you are fishing at night, cruising on an ATV, or want to add lighting on a truck, each 1.5 inch x 3 inch RGB LED accent light provides endless RGB color options. Swipe your finger to change the color, because these lights are designed for the included Heise control box, which can turn a smartphone or tablet into a remote control through the Heise RGB app. This free mobile app allows users to select colors through the color wheel, select pre-programmed flash patterns and colors, the option of color flashing with music, and even has a timer to choose when to turn on and off a particular pattern or color!
