timing lights?
Take this for what it's worth, but the recommended timing light for a MSD is this no-frills Craftsman p/n 2134. The part number varied over the years: 9-2134, 28-2134, 161-213400, but they are all basically the same.
The history on why it's the defacto choice (other than the MSD-branded unit) is that some magazine a long time ago tested a bunch of timing lights and this was the only one that worked the same as the MSD light. Maybe that ancient circuitry just ignored (or couldn't detect) the multi-spark of the MSD, whereas newer units tried to compensate? Who knows.
FWIW I have one that stays in the trailer with the race car for three reasons 1) it works, 2) it has a bright light - important when you're at the track on a sunny day, and 3) the dead-simple technology of these old tools makes them reliable. The thing is typical older over-engineered construction so it can take a beating. Is it really the best for an MSD? Who knows, and as they say YMMV.
These can be found on FleaBay almost always - probably as kids find them in Dad's garage and have no idea what it is or what it's for. But if you want one you'd better hurry - there's only about 30 for sale right now :D
Oh, and look for one with leads that are not all melted. I'm heading out to the shop now to develop a wireless Bluetooth unit :lol:
