MSD (multi spark discharge) "boxes" can make a sensitive timing light blink multiple times.

That's exactly right. I have an older Snap-ON digital tach/timing light and it does not work properly with multiple spark systems like an MDS 6,7 and such. Also have a dial back Fox Valley light, same issue. Best timing light I have ever used is a SUN 7501. They are on E-Bay all the time. It's a basic non-dial back light, but super bright, chrome case. One on E-bay right now for $29.00. Great light.
