Pet peeve, neighbors leave porch light on

I've watched videos on Nextdoor and lights don't seem to have any effect on thieves regardless of whether they are motion detecting or not. To me, motion detecting lights are like car alarms - you pay attention at the beginning or after something happens, but after a while you ignore it. Thieves know this and tend to assume you will ignore it as that is more likely. If you are one to check it, they just saunter away.

Even cameras are ignored, or worse, stolen right off the wall.

Camping, I personally prefer using a lantern or two when hanging out and a flashlight when walking around. Both have the positive of being turned off when you go inside for the night.
