I tend to forget to turn off the light sometimes, so I'd like to hook up a warning buzzer that will go off if headlights are on and ignition is off. Maybe trick it out and hook it up to the door as well. It's not difficult to design (I have done it in a couple of cars), and I have found several diagrams on the Internet, but I also remember seeing a kit somewere (JC Whitney, I believe). It said that you don't need to cut into the wiring, so I guess it hooks up to the fuse block. Of course, now when I want to get it, I can't find it. Does anyone know where to get these?
