ON A WAY FROM ROAD TRIP I WAS DRIVING ( NIGHT DRIVE) MY HEADLIGHTS WENT OUT IN MIDDLE OF DRIVING. I PULL ON SIDE OF THE ROAD TO SEE WHAT IS GOING ON AND THEN I SAW SMOKE PORING OUT OF MY DRIVER SIDE FOG LIGHT AND PASSENGER HEADLIGHT .OPEN THE HOOD AND SAW WHAT I REALLY DID NOT WANTED TO SEE A FIRE. I JUST WANA SAY BIG THANKS FOR SEMITRUCK DRIVER WHO WAS SO NICE TO STOP WITH HIS RIG AND TRY TO HELP ME WITH FIRE EXTINGUISHER. WHEN FIRE WAS OUT I PULL THE BULB OUT AND PLASTIC BULB SOCKET THE HOLD THE BULB WAS GONE MELTED. IM NOT TALKING ABOUT THE PLASTIC PART THAT IS ON BULB IS A PLASTIC PART THAT IS COMING FROM THE CAR ELECTRICAL WIRE THAT PLUGS IN TO THE BULB.SAME THING WAS WITH FOG LIGHT BULB ALL MELTED TO THE POINT WHERE THERE IS NO PLASTIC FOR BULB SOCKET. AFTER COUPLE MINUTES SEMITRUCK DRIVER TOLD ME TO FOLLOW HIM TO FIRST RESTAREA STOP SO I CAN BE SAFE NOT STANDING ON MIDDLE OF THE ROAD. WHEN I RESTART THE CAR AND TURN MY HEADLIGHTS ON ONLY ONE LIGHT WAS WORKING. FINALLY AFTER COUPLE MILES OF DRIVING WITH ONE HEADLIGHT AND FOLLOWING THE SEMITRUCK DRIVER WE CAME TO FIRST REST AREA STOP. AFTER LOOKING FOR COUPLE MINUTES SEMITRUCK DRIVER GAVE ME ELECTRICAL TAPE TO COVER THE WIRES SO THAT FIRE DOSE NOT START AGAIN. MAYBE IS HARD TO BELIEVE BUT I HAVE PHOTOS THAT I CAN SEND IT . I KNOW THERE IS A MERCEDES FORUM ON INTERNET ABOUT THIS PEOPLE HAVING THIS SAME PROBLEM. LIKE I SAID I HAVE PHOTOS THAT I CAN SEND IT IF YOU GUYS THING IS A MADE UP STORY. AND WORST THIN
