RECEIVED MESSAGE TO CHECK LEFT TAIL LIGHT, BRAKE LIGHT, BACK UP LIGHT AND TURN SIGNAL. I PURCHASED NEW BULBS TO REPLACE. WHEN I PULLED OUT THE BULB CARRIER, I NOTICED THAT THE AREA NEAR THE WIRING HAD MELTED AND THERE WAS DISCOLORATION. I CAN'T EVEN REMOVE THE PLUG HOUSING FROM THE CARRIER BECAUSE OF THE DAMAGE. I NOTICED THAT THERE WAS A RECALL IN OLDER MODELS FOR THE SAME EXACT ISSUE.
