You nailed it, particularly with my old US Army one. It's just a flashlight I've had forever that brings back some memories.

For the headlamp, if it's the old style Petzl headlamp that I think you have, then it's got a screw base terminal which are less common. They won't be physically compatible.


I was afraid you might say that. Yes, it's kind of an odd screw in type bulb, definitely not smooth like the PR type. I'm probably SOL here. Sigh.

That's what I thought, which is why I wondered why it said "replacement for Mag-Lite." The smaller Mini-Mag conversion kit definitely is for Mini-Mags only, so maybe the clueless ones in the purchasing dept. put "Mag-Lite" in the text assuming it was the same deal.
