When someone unlocks a modern car the cabin lights usually turn on. Some are LED and some are small incandescent light bulbs. Well I stopped to get my mail at the front of my complex and I am guessing the radio was off because when I was about to get out of my car the lights went out, which was accompanied with a high pitched noise. I was curious, naturally I made it do it a few more times before I concluded that the lamp was connected to a capacitor the capacitor draining as the lights dimmed cased this noise.
