I've had my 91 honda accord for almost a year and there has always been a wire right by the ignition with a small blue bulb attached to it. until a week ago it had never ever done anything and i wondered maybe..once..what it was for. well about a week ago it started lighting up every time i open my door. can anyone tell me what its there for? is it just so you can see the ignition? and why would it have never worked until now?
