I hope this is a one-off. No water leaks, etc. I have the remote programmed to turn on headlights and then reverse lights with a second press. Always worked fine. Last night I car drove down the lane and I fired them up to scare them away. Oddly today when I went to unlock my reverse lights came on. But not the headlights. I did not press anything besides unlock. There was no indication the alarm went off overnight.

Random weird Rover event or a sign that something should be looked at?
