Motion sensors are not necessarily much help because many users set the sensitivity and duration controls way too high. My idiot neighbors have bright unshielded porch lights and shielded flood lights on motion sensors but the sensitivity is set so high that birds flying by trigger the lights (slight exaggeration but not much) and the duration setting is also maxed out so that the lights stay on at least 30 min every time they are triggered. But since the sensitivity is set so high, the lights are always re-triggered (joggers, walkers, cars driving by, etc) before they shut off, so the lights are on continusly all night, every night, with rare exception. If the lights are off by some chance, I set them off myself if I put out the trash at the end of my driveway or pick up the newspaper early in the morning. Also full cutoff light fixtures are virtually impossible to find and not that much help. The light bulbs used by most security lights are so bright that the glare and reflected light from the beam hitting the house and ground are as bright as normal light fixtures. Our nightime view is completely destroyed by the neighbors shielded flood lights and it is impossible to use my telescope or camera in the front yard due solely to the bright reflected light. Light tresspass is like second hand smoke was 20 years ago. Smokers were assumed to have the absolute right to smoke just as light users are now assumed to have the right to blast light at their neighbors. Non smokers made a lot of noise and things changed.

That should be the Judge's ruling. A few of those and a full-cutoff light fixture would save a ton of legal fees...
