So i was making a room for armor sets and wanted to have a light on when there is armor on the armor stand and a light off when there is no armor on it. So i tried some things but all didnt work (Pressureplates/Observers) its for a multyplayer server so i dont have acces to command blocks. Is there a way to detect this ?

EDIT:Maybe something for in an update that Iron/Gold pressure plates can detect armor on an armor stand :)
