Hello, MK320 Wireless Keyboard and Mouse combo does not have illuminated keys which would indicate CAPS or NUMBER lock. However, through Logitech Options (free software) you can go through your settings->notifications->turn on caps lock indicator, there can be an indication on screen when either CAPS is pressed. Perhaps a K740 or K800 would be a better option as they have illuminated keys. I hope this information was helpful.
