If you're looking to mimic true strobe lighting, then you have to black out several frames at a time then continue for a few frames etc etc...
Try making a black track (generated media) to go over the top with the black events being a few frames long, followed by a few frames of transparent... a dashed line so to speak. First make one set then duplicate it. (copy/Paste paste Paste...) You have to experiment with this but when I do real strobes I use ~ 5'ish pulses per second.
You also want harsh single source lighting, the bump map can mimic this somewhat.
