Should the BMW headlight switch be placed at 0 or A position?

[Nick]

The BMW headlight switch has two different modes: 1. Place the vehicle switch at position O, which means the vehicle's light switch is in manual mode. You need to manually turn on the parking lights and low beams when using them. 2. Place the vehicle switch at position A, which means the vehicle is in automatic headlight mode. The vehicle's headlights will automatically turn on or off based on the ambient light level. More information about BMW headlights is as follows: 1. For daily use, you can place the headlight switch at position A: In this case, the vehicle's headlights are in automatic mode. When the front sensors detect insufficient external light, the vehicle will automatically turn on the parking lights and low beams, providing convenience to the driver without the need to manually operate the switch. 2. The function of BMW headlights: The driver does not need to operate the light switch; the vehicle will automatically turn on the low beams to illuminate the road for the driver. After exiting a tunnel, the headlights will automatically turn off based on sensor feedback.
