Hey guys! Please help! My Coupe lights don't.

Hey guys! Please help! My coupe lights don't disconnect when I open the door like it used to! I know it's a minor problem but its a big problem when I'm so used to it and I keep forgetting to turn off the lights! My battery is like a pancake! Is there anything I can do to connect the lights up to the door again do they switch off automatically! Iv jus had enough of the blonde comments I'm getting because I'm always leaving them on!
Many many thanks!
