The automatic headlights in your Nissan Altima utilize a light-sensitive sensor to adjust the headlights based on the driving conditions. This feature is useful for both daytime, nighttime, and inclement weather driving. The sensor is typically located at the front of the vehicle on the dashboard near where the dashboard and windshield meet. If your auto lights aren't functioning, the first step is to ensure nothing is obstructing the sensor. If the sensor appears clear, the next thing to inspect is the auto switch on the steering wheel stalk. If needed, replacing the entire stalk is a straightforward task.
