What causes the headlights of the new 3 Series to not turn off?

[IsabelleRose]

Damaged headlight switch, open or short circuit in the headlight switch wiring, or incorrect signals from the light and rain sensor on the windshield can all cause the headlights of the new 3 Series to not turn off. Check if the lights are functioning properly: During driving, vibrations from the car body can cause the direction of the light beam to shift, affecting driving safety. Regularly inspect the lights to ensure their direction is correct and brightness is not diminished. If any issues are found, adjustments should be made promptly. Replace bulbs periodically: Car headlight bulbs should typically be replaced every 50,000 kilometers or approximately every 2 years. It is advisable to replace bulbs regularly. It is best to replace both bulbs simultaneously to avoid uneven brightness between the two sides. Additionally, when selecting bulbs, avoid inferior quality ones and choose those suitable for your vehicle model.
