Make Background light up to simulate Lights ON

[victor.back]

Hi, easiest way for me - using just svg icons with Alpha channel used (transparency). I use grey icon if light is off and yellow when is on. For that you need status of lighting object. At your plan you should select additional icons, and if status value = 0 use grey icon, if from 1 to 100 than yellow. Icons are transparent, so you will see your plan

Icons are in attach. You can use free inkscape editor to make changes. Even you can make rotating svg icons if you need. Read more at forum about icons.

BR,
