Its average battery of the car has between 60 and 100 hours of capacity. Thus, the time until the battery is completely drained is theoretically between 4.8 and 8 hours. Now, an hourly capacity of the battery decreases with the increase of the amperage bond, so it seems more realistic between 4 and 7 hours.

Some people can leave the lights on for 4 hours and they won't die, some people go back to a dead battery if they've gone away for so long.

Is it safe to leave a light on during this period? Assuming that the lamp does not exceed the rated lighting power, it is safe to leave the lamp on for your vacation. In other words, do not use a 100watt lamp in a 60watt lamp.

How long can LED lights be left on? Many LEDs have a nominal useful life of up to 50,000 hours. This is about 50 times greater than an incandescent type, 20-25 times greater than a halogen type, and 8-10 times greater than a CFL type.

The typical incandescent lamps last between 1000 and 2000 hours. But as for LED replacements, the useful life of the lamp is usually mentioned between 25,000 and 50,000 hours. The life of the lamp, and the reduced energy used to create the same amount of light, is what makes this technology so promising.
