Play Actor Sequence in Sequencer - "Alarm" lights in scene


In order to get the effect of emergency lights going slowly lower and higher in intensity over the whole scene I animated a blueprint actor with two light sources in an actor sequence ( within the blueprint to use the working blueprint several times in the scene.

When i hit play in the editor it works fine but it is not functioning when playing level sequence.
I can not manage to trigger the animation/event to play in level sequencer.

I think there could be a solution here

or here

but i can not figure out the details.

Can someone please help?

Tried to create a custom event in event graph… don’t know if this can work

this is the blueprint wiht actor sequencer for two light sources
