What are the consequences of forgetting to turn off the low beam lights before turning off the engine?

[LeBenjamin]

Forgetting to turn off the low beam lights before turning off the engine can have the following consequences: For vehicle models without an automatic light-off function, the lights will remain on until the battery is completely drained. If the battery runs out of power or has insufficient power, the vehicle may fail to start. Therefore, it is essential to check whether any electrical devices are left on before exiting the car. If the car headlights have an automatic shut-off function, they will turn off automatically after the engine is turned off. Low beam lights are designed for close-range illumination, featuring a wide coverage area but a short projection distance, with non-adjustable focus. It is mandatory to turn on the low beam lights when driving in dark areas without streetlights, during dusk when visibility is low, or at dawn when light is just appearing.
