Last night it was lightly misting at my house and thunder off in the distance. Every time before it thundered - about 3 seconds - my motion lights would all go on at the same time. Anyone know what would make them do this? It was not raining hard or anything enough to turn them on and the thunder was miles in the distance. Maybe something electrical?

Depends on how the motion sensor works. If it uses radio waves then lightning could easily set them off. Ever drive around with your radio on and a big lightnight strikes nearby, and then your radio signal goes to static for a couple seconds? Lightning gives off lots of radio waves.

It wouldn't matter much if it was 1 or 10 or 100 miles away, as radio waves travel at the speed of light.

well, makes sense i guess seeing how the it matches the lightning/thunder format. But it has never done it before which is why I was asking. So maybe it was a different kind of lightning.
