Why do my headlights come on when I start my car?

Why do headlights move?

Do headlights turn on when you start the car?

Today’s automatic headlamps come on whenever the switch is in the “auto” position and it’s dark enough to require them. They use a photoelectric sensor that’s usually mounted on top of the dash, or on the windshield near the rearview mirror. … It’s because these can block the sensor and prevent the lights from working.

What causes headlights to go on and off while driving?

What are the headlights that move up a down?

The genius of adaptive headlights is that they move up or down according to the position of the vehicle. They react to the speed, steering radius, and level of the surface, then automatically adjust to what the driver is doing and the road conditions ahead.
