On some cars it is a precautionary measure that the headlights stay on even after the key is removed from the ignition, you will often find they will turn off after the driver's door is opened and then closed again (when the key has been removed)
This precaution is built in incase the car breaks down in dangerous places such as the hard shoulder on a motorway, the lights staying on provides other road users with visibility of your car, especially in dark conditions.
Hope this helped :)
They stay on cause they runnin off the battery. there should be a car headlights switch somewhere by your spedometer stuff...
Headlights run off the battery not the ignition...

on what vehicle?
i would assume you need to turn your headlights off as they are the most common reason for the beeping after you turn off the car. My headlights are off and the car is still beeping
Firstly, turn the ignition on but don't start the engine, then turn the headlights on, then off, then turn them back on, then off again. (so twice on, twice off) the car should beep at you twice indicating this function has been switched on. To switch off, repeat the same steps above and the car will only beep once.
There are a couple of different times when you'd turn off your headlights. You'd turn off your headlights when the car is off for example.

why do my head lights stay on when shut off after 20 minuets still on
Due to laws of inertia of motion the blades continue to move because as the current is switched off the blades still remain in motion. By aryan nath utpal.(check me out at facebook)
Headlights in the US are generally positive switched, because the best source of return current is vehicle ground, and US cars are generally a positive voltage system. However, if Daytime Running Lights (DRL) are employed, often the high beams are wired in series, so as to illuminate at about one quarter power, so the concept of which end is switched becomes vague. Usually, one is positive switched, and the other is positive switched between switched positive and the negative side of the first.
