I would be verrrrry leary about replacing those headlights with Litronics or anything that is going to cost you more $$$.
1- the dude that stole your lights didn't just stumble upon your car. He noticed your car parked outside and made an appointment to visit your car at 4am when everyone was sleeping. I'm betting he used a van to block the view of passing cars.
2-this person is probably roaming the area and he will be back to pump that well again. Or he will tell one of his Porsche-familiar parts theives about his score.

You need to move out to a different area or find garaged parking.

This is why I never leave my car with the top down when I'm running errands.
These guys know how to get in and out quick. I'd say you are lucky they weren't Litronics that required disconnecting wires, these idiots have known to do big $$$ damage to the electrics.
