When a vehicle with bright lights is approaching, you should avoid looking directly at the headlights, as this can impair your vision. Instead, focus on the right edge of the road to help maintain your lane. If necessary, reduce your speed and be prepared to pull over if the oncoming vehicle is too close. Using your vehicle's sun visors can also help reduce glare.
If you are driving with your bright lights on and can see an approaching vehicle, you should turn off your bright lights immediately.
500ft if it's oncoming. 350ft if you're coming up behind someone.
If you can see the oncoming vehicle then he can see you. Dim your lights at that time.
500 feet if the vehicle is coming to you, 300 feet if you are following it.
Although the lights should be dipped when approaching another vehicle so they aren't bright, the best place to look would be at the edge of the road on your side; you will still be able to see most of what is on the road ahead of you, but without looking directly at the bright lights.
You should only use your parking lights when your vehicle is parked or stopped in a dark area. They should not be used while driving as they are not bright enough to properly illuminate the road.
Outside walls can be as bright as one wants them to be. Some prefer to have very bright lights to light up an area, while others prefer dimmer lights to accent a spot.
It perfectly depends on where you live or drive. You should dim your headlights right when you see another vehicle in front of you or right when you see the lights of another vehicle. It doesn't matter if you are seeing the tail lamp (both of you are traveling in the same direction), you should dim the lights or else it is going to make difficulties for the driver in front.
Low beam headlights and fog lights if the vehicle has fog lights.
Highbeam headlights should not be used within city limits when there is oncoming traffic or when driving behind another vehicle, as the bright lights can blind other drivers and create a safety hazard.
