I had an older Vistalite (does anyone else still use these??) that was stolen off my bike that was locked in a stairwell. They left the battery and cord, just took the lamp. I was prepared to replace it and started thinking about it. I printed out a sign briefly explaining that it would do the person no good and asking for it's return. The next day it was left on the the seat of my bike!! Unexpected and I still use it!!
