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

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.
Last time I made this exact absent-minded mistake - after parking and turning off the engine, I forgot to switch off the low beams. When I went out for an errand at midnight, the car wouldn't start at all. After struggling for a while, I had to call a friend to help jump-start it. The mechanic later told me that keeping the low beams on continuously drains the battery. Even with the engine off, it will completely deplete the battery. It doesn't take long before the battery is empty, and frequent deep discharges can permanently damage the battery plates, shortening its lifespan and requiring expensive replacement. My lesson learned: develop the habit of turning off lights when parking. Don't underestimate this small thing - batteries are more prone to issues in winter. Since that incident, I always double-check that lights are off before leaving, saving both trouble and money. Remember, momentary negligence can lead to long-term consequences, especially for older cars without automatic features - extra vigilance is needed.
