My trailer got hit one time, and the rear signal broke. I didn't notice until I saw a note under my windshield wiper. Some lady had hit it, but she left her contact info and everything. I called her back just to see what happened and said it was fine. I was working at West Marine that summer, and could get a great deal on a new taillight fixture, so thankfully it wasn't a big deal.
Props to people who are honorable enough to leave notes and own up
