How to use Lesser Insignia of Warden?

I purchased the lesser insignia of warden, but can't figure out how they are used. It would seem that it could be used just like a glyph, but it is always grayed out in battle, whether it is in PvP, PvE, aoh, dot, or 7b. I searched the forum and did not see this addressed, so if someone could help, I would appreciate it and pass it along to others. Thanks!
