Adjustable advance timing lights are not recommended for use on MSD ignitions. Plenty of information/confirmation out there with a little Goggleing.

MSD sells their own light, both 12v and self powered - or - you can try to find an old Ferret/MSD non-adjustable light - or - you can pick up a mint or NOS Sears/Penske 2138 light, this was sold relabeled by MSD years ago under part #8990. This is what I've used for decades. They are out there.

I've seen people say they've had good results with some of the self-powered lights (Flaming River, etc) available as well, but have no personal experience with them.
