That's not really that odd to hear. I found the screws removed from the headlight bezel on my '85 Lincoln. They're chrome and apparently not easy to find in good shape. Luckily, Charger the wonder chihuahua must have scared them away. He was barking like crazy that night so I went out to check the perimeter. Maybe it was the sight of a 290 lbs angry guy walking around in his boxers that scared them off.
Here's another story of a hit on a NJ dealership -- they took 36 pairs of lamps:
