Hours is enough to empty them. If I see them parked in front of our house late in the evening, I don’t think they’re going to go out anymore today. It’s fat more likely that they forgot to turn them off than that they intentionally kept them on.

Fortunately, they rarely flash, but burn continuously. I think the flashing ones are illegal here, and they can be super annoying.

Good man.

I do the same, but with bicycle lights that people have left on. I know how annoying it is to find your battery empty.
