What are the consequences of leaving headlights on after the car is turned off?

Leaving the headlights on after the car is turned off can lead to battery drain and shortened battery life. Here are the related details: Battery drain situation: When parking at night with the engine off, the alternator stops working, and the car's battery takes over to power the headlights. If the headlights are left on all night, the battery's power will continue to be consumed until it is completely depleted. Shortening the battery's lifespan: If the vehicle's battery is drained, it will require a jump start, but this method will shorten the battery's lifespan. Typically, a new car's original battery can last 3 years or more under normal conditions. However, if the headlights are frequently left on, it will wear out the battery, and in severe cases, the battery may fail in as little as 3 months.
