A backlight gaming keyboard and mouse set enhances gameplay with visible keys and customizable lights, featuring a wired or wireless USB connection for plug-and-play setup. Keyboards offer durable, tactile "mechanical-feeling" keys with features like anti-ghosting and multimedia keys, while mice feature high DPI adjustable sensitivity and ergonomic, light-up designs. These sets typically come with a single USB receiver for wireless models and are compatible with most operating systems, including Windows, Mac, and Linux.
