What can you do if you inadvertently set off a motion detector that turns on a light on Shabbos - Can you keep walking? If I have one do I have to shut it off before Shabbos?

Dayan Nueschloss ZT"L told me that it was not a problem to walk by such a light on Shabbos. I heard the same in the name of Dayan Falk.

Rav Ephraim Greenblatt told me that it probably is not a problem, but in his opinion if it can be avoided, then you should. He told me that he asked and reminded his gentile neighbors to turn them off before Shabbos and they were very good about it. (But that was in Memphis, in the buckle of the Southern Bible Belt)

Keep walking. Rav Wosner says that if you're just walking normally then there's no issue.

I infer that this is a Psik Reisha D'Lo Nicha Ley on a Melacha Derabanan, as per the rationale here –  Zachariah Oct 1 '13 at 13:21
