Looped animation to a trigger

[Scorpy_cfs 10]

Gudday,

Just wondering if anyone might be able to help me with a script that allows one to trigger a looped animation, like switching on a radar dish and being able to switch it off again? Would it be feasible to add a light much like a lighthouse to such a rotating item that would also switch on when the animation begins to rotate, and off when it ceases?

Much thanks in advance.
