I can't speak exactly to NJ but in 2006 it became law pretty much everywhere.
yes
If it's raining enough for wipers on you have to have headlights on. Intermittent wiper its not required.
You should cut on your car lights at dusk or any time that the law requires you to have them on. Some states require you to have car lights on whenever your windshield wipers are on for rain.
Not if headlights are reqired by law.
No, if a windshield seal is broken and leaks, it is not covered under the windshield law in Florida. You must have a cracked or broken windshield in order to be covered in this instance.
Twilight Sentinel was introduced in the 60's by GM. It automatically turns on headlamps in low light conditions such as dark parking garages and at dusk, turning them off when it senses daylight. Newer versions are connected to the RainSense automatic windshield wipers and will automatically turn on the headlamps when the wipers are on (now a law in some states) The twilight sentinel is a slide switch that lets you control how long your headlights will stay on after you turn the engine off. This allows you to have lights while you are getting out of the car. This is useful if you park in a dark garage and avoids stumbling around.
Many people refer to headlamps as headlights. The main purpose of head lamps is still allow the driver of a vehicle to see during night hours. The headlamps also allows the driver to see better in bad weather. In fact some states require by law that headlamps must be on whenever a vehicles windshield wipers are active. So in conclusion a vehicles headlamp is used primarily to allow the driver to see when it is dark .
NO
You would not drive it at night or when the law says you must display headlights.

It will depend on state law. In general though, usually at sunset (before dusk and dark). Some people use them whenever its raining and their wipers are turned on. Some people use them all the time for safety...like me.In
(Weber's law explains why you don't notice your headlights are on in the daytime)
