If you have a rack-mounted audio/video system, then you know what it's like to grope around trying to make connections in the ill-lit recesses in the back of your cabinet. With the Corona LED light, you can leave that experience in the past. This thin strip of LED lights mounts on your rear rack rail. Its powerfully bright light makes it easy to see wires, terminals, and terminal labels. The Corona comes with its own AC power adapter, and an on/off switch.
