Flickering light with interval

[timpeters]

I'm working on a scene, which has a flickering light.

I tried to make the light flickering, but can't find a way to do a proper timing with an interval.
The result I'm looking for is something like the lights on the wing of this drone (starts at 2:43):

Created already this (see attachments), based on this tutorial. But can't find a way to add an interval

Is there a any correct way to make the flickering with an interval?

If you want something like the drone light, it's just a simple set of pulses with a delay interval. Why not just keyframe one cycle, then use Key>Cycle in the curve editor to dupe it as many times as you need? Don't make life more complicated than it needs to be.
