Pioneer DVR-116DBK Status Light

Hi all

Yesterday I bought a Pioneer DVR-116DBK to replace my old 110d. Drive seems to burn perfect but I am concerned about the status light. When not in use the green status light dims right down so it is actually still on. It gets fully bright when drive is in use. Then dims right down so it is always on. Is this normal? The firmware that came with the drive is 1.07

Any help on this would be great. I looked around but cant seem to find out from anyone if this is normal

Many Thanks

Update to the 1.09 firmware.
