No, you shouldn’t turn off your lights at night. That makes you invisible to other drivers, pedestrians, bicyclists, motorcyclists, truckers on the road. It also reduces your ability to see the road ahead of you. It would be extremely dangerous for you and for others.
You should also turn your lights on during the day if it is a dark day or it is raining, snowing, foggy, etc. In this case, it’s not about you seeing the road, you want other people to be able to see you.
Dim your lights when you have oncoming traffic or are coming up on people from behind.
If your lights are dimmed and you are still getting flashed by other oncoming drivers, go to a shop and have your lights aligned properly so they don’t blind people.
