“My wife told me her headlight was burned out. When I replaced the bulb, I found the insulation on the electrical harness and headlights is deteriorating leaving exposed bare wires causing electrical shorting, equipment failures, electrical fires, leading to potentially serious life threatening accidents. Mercedes benz is not supplying a fix as reported by multiple owners. Also extended warranty insurers are denying coverage due to the wide spread defect across the mercedes benz models.”

I decided to try to replace the bulb myself, but I found that the insulation on the electrical harness leading the headlight connectors had deteriorated to the point that the wires are bare, causing electrical shorting, equipment failure, leading to potential electrical fire which may cause serious life threatening accidents. …”
