Can this be used to select/deselect layers on scenes?

For example: Keyframe animation of 400 frames at 25 fps. Animation is perfect. I want to add a blinking light on/off every half second. Can this be used to add that light component on/off to a group of 14 frames and off for 14 frames via this type of programming?

May be I think you can adjust keyframe little bit more instead of 25 fps.
