I have a similar problem, we have an Arab neighbour who built this fancy house with motion sensor security lights at the front, we spoke to him about limiting the sensitivity to just his front drive but he didn’t do it, so on shabbos we have a problem walking past. Some ppl on some ppl on the street cross the road, but we spoke to our rov who said it’s fine to walk past, since we don’t benefit from the light and in fact don’t want it. It’s quite complicated but speak to your rav.
With darkness sensor lights, If they are security lights then the sensor would be high up most times directly under the light or next to it, so usually the light is placed near the top of a wall so it’s to high up to catch your shadows.
