Any way to wire in a lights on when car turned off beeping sound?

Put your buzzer back in, your car came with that feature

Hey guys, so I hate the fact that when I leave my lights on in the e30... I forget to turn them off. Ugh! Annoys me because one day it will drain the battery. So like the title states. Anyone know how to wire something up or hook something up that's makes a sound when the lights are on, and the key is off?

It can be done but the good thing is that when you turn the engine off the lights turn off as well. Only the parking lights stay on regardless how you left the light switch.
