Brake Light On problems of the 2008 Mercedes Benz C300

Received warning on dash to check rear driver tail light. Took the car in to the dealer to get it checked out and was told the wires from the tail light were melted from the electrical panel and my car is running on back up lights. The only solution is to replace the entire electrical back light system since the melted wires would eventually damage the entire brake light system. The cost to repair $900. Car smells burnt inside, and in the trunk. I am afraid of a fire, and getting rear ended if my brake lights stop working.

The brown wire in the right hand brake light melted through the wire harness and started to melt the light board. This is a fire waiting to happen, I smelt burning in my car when I was driving. The break light no longer works.
