OK,now this makes a little more sense. I gather you have been convicted or charged with some alcohol related offense. And that you are under house arrest with some sort of monitoring device.

If the device came with a manual, then read it, it should explain what the lLEDs mean. If not, check the manufacturer's web site or contact them.
