This should be already the case - your headlights
should turn off automatically when you turn off the key. But I know what you mean. The parking/running lights will stay illuminated.
But, this is can be changed without much trouble. It's a 10 minute job if you've ever taken out your headlight switch. If you haven't, then you can expect to double that time.
Our headlight switch is a wonderful piece of simple wiring/switching gear in our cars. Power goes in and depending on the position of the headlight switch (off/position 1/position 2) and the ignition key (off or run), it will direct that power to a number of different standard sized terminal pins located on its back.

If you take a gander at this little matrix I made up a few years back, you can see which conditions send the power to which terminals. You can see that the headlights should be ON whenever the ignition key is in the RUN position and the headlight switch is in position 2. Makes sense, right?
But how to get the running lights to go off with the ignition key and on when you pull the headlight switch out to either on position? If you take a look where it indicates terminal N, you will see that it is only pushing power whenever the ignition switch is ON and the headlight switch is in position 1 or 2.
Notice that I indicated on that chart N is for the license plate and ash tray lights? Go out now and check your car. Hit your parking lights only with the key off. All your corner lights will come on. Check the license light - should be dark. Now turn your ignition to the RUN position. Your license light just came on, yes? Cool right?
So how will all this mumbo jumbo help your parking lights turn off with the ignition? Well, also refer to that same chart and you will see that the parking lights indicated (and wired) conveniently as 58R and 58L for your parking lights on the right and left (thank you Captain Obvious). Yeah, so what...?
So if you move your parking light wires to terminal N, they will turn off with the ignition key. If you leave your headlight switch on any position, or if you forget to turn them off, all the lights will go out with the ignition key.
One caveat and some advice: if you do this modification, it's probably a good idea to document which wires you moved from and to, perhaps with little labels behind the switch.
ALSO, and this is important: be sure to move ALL the wires from any of the terminals that you don't want to run when the ignition is off that might run when the headlights are on. This includes anything on pin 30 which is HOT at all times and 58A which I think
may be the dash lights, pin 58 and pin 57 which is for the little green light that lights up on your tach when you're driving about with just your running lights turned on. Anything that is on any of those pins that are energized when the light switch is in any position other that off will be energized if they aren't also moved to pin N.
EDIT: Just to be clear, your headlight switch still has to be on for your headlights to work but it wouldn't have to be turned off as they'd go out with the ignition switch off. And there will be quite a few wires to attach to terminal N, so you'd have to use bridging clips or MacGuyver something together to get them on there.
Good luck to anyone trying this out. Think about what you're doing before you do it and test, test, test, because it would really suck to want to go for a drive and have a flat battery because your glove box light has been on for the last couple weeks...
