Really. As already admitted by one poster he failed to properly lock the headlight after removal. I'll bet most if not all of the headlights have been removed and not properly reinstalled.

The issue is the cam lock. To be stable it has to be "over centered" by a few degrees. In my case I found a small pebble in the guide track, which I assume did not let the light get fully seated. So when I locked the cam lock, it felt secure, it was centered or slightly over centered, but not enough to keep it from vibrating backwards. So the deign flaw is: there is no way to tell how far over centered the cam is. You can feel it over center, but beyond that you cant tell how far.

I guess I should blame my first PCA instructor for that... those damn cup car guys... sheesh 
How on earth did you get the dealer to pay the 2nd one?
I was concerned about that as well - to some extent, I'm happy it just came off and wasn't flapping around still attached to the wire harness.
And moving forward, i shall do likewise!!!
That's a good question? I want to say user error but the headlights haven't been out for a while. To have wiggled loose is kinda crazy given the locking mechanism... I'm suspicious as well.
That's a good idea for a track car - i'm sure it's much cheaper than an OEM headlight housing.
Happened to me once after removing the front bumper of my 991 to fix the 3rd radiator "blank" filler. I put everything back together and also put in new brake pads the same day. Took the car out to bed-in the pads. Blammo. Out came the light, dangling on the highway. It didn't fall off, though, and I was able to replace it in its hole. No harm done. A few scratches on the PPF. Scary, though!
You seriously lucked out that it just popped out. When my came loose, I was concerned about running it over but luckily I was on the brakes.. in the video, you can hear it scraping down the pavement.
EDIT: Upon further inspection, it turned out I didn't lock the light in place properly when I put everything back together. It felt like everything popped properly back with the headlight tool, but alas...

The dealer installed it. They couldn't say it was improperly installed since they did it.

The sad thing is, from an engineering perspective, the way you secure the light from the frunk makes it a perfect candidate for a simple pin. Push a pin through a mated hole in the headlight assembly, if you can outbrake that then your headlight isn’t your primary concern.

Hopefully I'll be making it out an event this year.
