Anyone please?

Only when its dark i've noticed it.

Hi, Recently I purchased a Lexus IS220D 2006 plate. The only problem I seem to be having, is the headlights seem to stay on at night even after the car is locked, and it doesn't seem to switch off automatically. I have left them on "auto". To switch them off, I have to unlock the door, close it and lock it a few times, only then they switch off. Is there anyway I can solve this? Thanks
