Headlight went off while driving, when i went to replace the bulb discovered that all the wiring inside the headlights have the insulation crumbling off causing exposed bare wires to short together. this is unacceptable on a car that is only 7 years old. i researched on the internet and found that is a common problem on bmws. if your warranty expired bmw will not fix it. this is especially dangerous at night went the headlight start to flicker on and off. *tr
